ASTM A609/A609M-12(2023)(Practice)
Standard Practice for Castings, Carbon, Low-Alloy, and Martensitic Stainless Steel, Ultrasonic Examination Thereof

ABSTRACT
This test method deals with the procedures for the standard practice of performing pulse-echo ultrasonic examination of heat-treated carbon, low-alloy, and martensitic stainless steel castings by the longitudinal-beam technique. Calibration shall be executed by either flat-bottomed hole or back-wall reflection. The instrument to be used for examination shall be the ultrasonic, pulsed, reflection type. Personnel and equipment qualifications, materials preparation, casting and test conditions, data recording methods, and the acceptance standards for both types of testing procedure are all detailed thoroughly.
SCOPE
1.1 This practice2 covers the standards and procedures for the pulse-echo ultrasonic examination of heat-treated carbon, low-alloy, and martensitic stainless steel castings.  
1.2 This practice is to be used whenever the inquiry, contract, order, or specification states that castings are to be subjected to ultrasonic examination in accordance with Practice A609/A609M.  
1.3 This practice contains two procedures. Procedure A is the original A609/A609M practice and requires calibration using a series of test blocks containing flat-bottomed holes. It also provides supplementary requirements for angle beam testing. Procedure B requires calibration using a back wall reflection from a series of solid calibration blocks.  
Note 1: Ultrasonic examination and radiography are not directly comparable. This examination technique is intended to complement Guide E94/E94M in the detection of discontinuities.  
1.4 Supplementary requirements of an optional nature are provided for use at the option of the purchaser. The supplementary requirements shall apply only when specified individually by the purchaser in the purchase order or contract.  
1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.  
1.5.1 Within the text, the SI units are shown in brackets.  
1.5.2 This practice is expressed in both inch-pound units and SI units; however, unless the purchase order or contract specifies the applicable M-specification designation (SI units), the inch-pound units shall apply.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM A747/A747M-23(Specification)
Standard Specification for Steel Castings, Stainless, Precipitation Hardening

ABSTRACT
This specification covers iron-chromium-nickel-copper corrosion resistance steel castings capable of being strengthened by precipitation hardening heat treatment. The steel shall be made by electric furnace process with or without separate refining such as argon-oxygen decarburization. The steel materials shall also undergo homogenization heat treatment, solution annealing heat treatment, precipitation hardening and shall conform to the required values of temperature and time and cooling treatment. The materials shall conform to the required chemical compositions of carbon, manganese, phosphorus, sulfur, silicon, chromium, nickel, copper, columbium, and nitrogen.
SCOPE
1.1 This specification covers iron-chromium-nickel-copper corrosion-resistant steel castings, capable of being strengthened by precipitation hardening heat treatment.  
1.2 These castings may be used in services requiring corrosion resistance and high strengths at temperatures up to 600 °F [315 °C]. They may be machined in the solution heat-treated condition and subsequently precipitation hardened to the desired high-strength mechanical properties specified in Table S51.1 with little danger of cracking or distortion.  
1.3 The material is not intended for use in the solution heat-treated condition.  
Note 1: If the service environment in which the material is to be used is considered conducive to stress-corrosion cracking, precipitation hardening should be performed at a temperature that will minimize the susceptibility of the material to this type of attack.  
1.4 Supplementary requirements of an optional nature are provided for use at the option of the purchaser. The supplementary requirements shall apply only when specified individually by the purchaser in the purchase order or contract.  
1.5 This specification is expressed in both inch-pound units and in SI units; however, unless the purchase order or contract specifies the applicable M-specification designation (SI units), the inch-pound units shall apply.  
1.6 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. Within the text, the SI units are shown in brackets.  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM A757/A757M-22(Specification)
Standard Specification for Steel Castings, Ferritic and Martensitic, for Pressure-Containing and Other Applications, for Low-Temperature Service

ABSTRACT
This specification covers carbon and alloy steel castings for pressure-containing and other applications intended primarily for petroleum and gas pipelines in areas subject to low-ambient temperatures. Castings shall be heat treated by normalizing and tempering or liquid quenching and tempering. The steel shall be made by the electric furnace process or other primary processes. Heat and product analyses shall be performed on the material and the chemical composition shall conform to the prescribed values for carbon, manganese, nickel, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, also for residual elements like vanadium, copper, nickel, chromium, molybdenum, and tungsten. Tensile test shall be made and the mechanical properties thus determined shall conform to the required tensile strength, yield strength, elongation, and reduction of area. Charpy V-notch testing shall be done to determine the impact properties on each heat by specimen type like coupons representing the weld deposits and coupons representing the heat-affected zone. Impact properties shall also be determined on both the heat-affected zone of the base metal and the weld metal of the welding procedure qualification test. After machining, each pressure-containing casting shall undergo hydrostatic pressure testing and shall not leak.
SCOPE
1.1 This specification covers carbon and alloy steel castings for pressure-containing and other applications intended primarily for petroleum and gas pipelines in areas subject to low-ambient temperatures. Castings shall be heat treated by normalizing and tempering or liquid quenching and tempering. All classes are weldable under proper conditions. Hardenability of some grades may limit usable section size.  
1.2 The values stated in either inch-pound units or SI units are to be regarded separately as standard. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.  
1.2.1 Unless the order specifies an “M” designation, the material shall be furnished to inch-pound units.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM A217/A217M-22(Specification)
Standard Specification for Steel Castings, Martensitic Stainless and Alloy, for Pressure-Containing Parts, Suitable for High-Temperature Service

ABSTRACT
This specification covers steel castings, martensitic stainless steel and alloys steel castings for valves, flanges, fittings, and other pressure-containing parts intended primarily for high-temperature and corrosive service. The grades of steels covered here are: Grade WC1, Grade WC4, Grade WC5, Grade WC6, Grade WC9, Grade WC11, Grade C5, Grade C12, Grade C12A, and Grade CA15. Heat treatment shall consist of normalizing and tempering for Grade C12A and tempering for all other grades. Heat treatments shall be performed after castings have been allowed to cool. Heat and product analyses shall be performed wherein specimens shall conform to required chemical composition of carbon, molybdenum, chromium, nickel, vanadium, manganese, phosphorus, sulfur, silicon, columbium, nitrogen, aluminum, copper, titanium, tungsten, and zirconium. The surface of the casting shall be examined visually and shall be free of adhering sand, scale, cracks and hot tears. Steels shall undergo tension test, and shall conform to the following mechanical requirements: tensile strength, yield strength, elongation, and reduction of area.
SCOPE
1.1 This specification2 covers martensitic stainless steel and alloy steel castings for valves, flanges, fittings, and other pressure-containing parts (Note 1) intended primarily for high-temperature and corrosive service (Note 2).  
1.2 One grade of martensitic stainless steel and nine grades of ferritic alloy steel are covered. Selection will depend on design and service conditions, mechanical properties, and the high-temperature and corrosion-resistant characteristics (Note 3).
Note 1: Carbon steel castings for pressure-containing parts are covered by Specification A216/A216M. Low alloy quench-and-tempered grades equivalent to Specification A217/A217M grades may be found in both Specifications A352/A352M and A487/A487M.
Note 2: The grades covered by this specification represent materials that are generally suitable for assembly with other castings or wrought steel parts by fusion welding. It is not intended to imply that these grades possess equal degrees of weldability; therefore, it is the responsibility of the purchaser to establish for himself a suitable welding technique. Since these grades possess varying degrees of suitability for high-temperature and corrosion-resistant service, it is also the responsibility of the purchaser to determine which grade shall be furnished, due consideration being given to the requirements of the applicable construction codes.
Note 3: The committee formulating this specification has included nine grades of materials that are considered to represent basic types of ferritic alloy steels suitable for valves, flanges, fittings, and other pressure-containing parts. Additional alloy steels that may better fulfill certain types of service will be considered for inclusion in this specification by the committee as the need becomes apparent.  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM A487/A487M-21(Specification)
Standard Specification for Steel Castings Suitable for Pressure Service

ABSTRACT
This specification covers low-alloy steel and martensitic stainless steels in the normalized and tempered, or quenched and tempered conditions, suitable for pressure-containing parts. All castings shall receive the specified heat treatment requirement: austenitizing temperature, medium, quenching cool, and tempering temperature. Preliminary heat treatment and multiple tempering are permitted. Recording-type pyrometers shall be used to control the furnace temperature. The steel shall conform to the required chemical composition for carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, vanadium, boron, and copper. Residual elements include: copper, nickel, chromium, tungsten, molybdenum, and vanadium. Tensile properties of the steel shall conform to the requirements for tensile strength, yield strength, elongation, reduction of area, hardness, and maximum thickness. Product analysis tolerance is specified. Repair by welding may be done.
SCOPE
1.1 This specification2 covers low-alloy steels and martensitic stainless steels in the normalized and tempered, or quenched and tempered, condition suitable for pressure-containing parts. The weldability of the classes in this specification varies from readily weldable to weldable only with adequate precautions, and the weldability of each class should be considered prior to assembly by fusion welding.  
1.2 Selection will depend on design, mechanical, and service conditions. Users should note that hardenability of some of the grades mentioned may restrict the maximum size at which the required mechanical properties are obtained.  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.  
1.3.1 Within the text, the SI units are shown in brackets.

ASTM A1091/A1091M-21(Specification)
Standard Specification for Steel Castings, Creep-Strength Enhanced Ferritic Alloy, for Pressure-Containing Parts, Suitable for High-Temperature Service

ABSTRACT
This specification covers general requirements for creep-strength enhanced alloy steel castings for valves, flanges, fittings, and other pressure-containing parts intended primarily for high-temperature service. However, the castings are not restricted to such applications, and may be used for other applications for which the attributes of the material, as defined by this specification, are suitable. The specification includes one grade of martensitic alloy steel, Grade C91, which is provided in two classes, differentiated by the type of heat treatment after weld repairs.
This specification also prescribes the general conditions for delivery, including those for investment castings, as well as the requirements for ordering information; materials and manufacture (heat-treatment and machining); chemical composition; testing of mechanical properties (tensile testing and hardness testing); quality of castings; rework, weld repair, and retreatment; and certification and marking of castings.
SCOPE
1.1 This specification covers creep-strength enhanced alloy steel castings for valves, flanges, fittings, and other pressure-containing parts intended primarily for high-temperature service (see Note 1). However, they are not restricted to such applications and the castings may be used for other applications for which the attributes of the material, as defined by this specification, are suitable.  
1.2 One grade of martensitic alloy steel, Grade C91 (UNS Number J84090), is covered (see Note 2). It is provided in two classes, differentiated by the type of heat treatment after welding. This and similar steels are characterized by a predominantly tempered martensitic or tempered Bainitic microstructure that is stabilized by the precipitation of temper-resistant particles at various precipitate nucleation sites in the microstructure. Such steels are designed to have creep-rupture strengths significantly superior to those of alloys of nominally similar compositions, but in which the precipitates or nucleation sites are absent. Since this crucial difference cannot be revealed by room-temperature mechanical property tests, these alloys require tighter controls on manufacturing and processing.
Note 1: The grades covered by this specification represent materials that are generally suitable for assembly with other castings or wrought steel parts by fusion welding. It is not intended to imply that these grades possess equal degrees of weldability; therefore, it is the responsibility of the purchaser to establish a suitable welding technique. Since these grades possess varying degrees of suitability for high-temperature service, it is also the responsibility of the purchaser to determine which grade shall be furnished, due consideration being given to the requirements of the applicable construction codes.
Note 2: The committee formulating this specification has included one grade of material that is considered to represent a type of ferritic alloy steel suitable for valves, flanges, fittings, and other pressure-containing parts. Additional alloy steels will be considered for inclusion in this specification by the committee as the need becomes apparent.  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM
ASTM A447/A447M-11(2021)(Specification)
Standard Specification for Steel Castings, Chromium-Nickel-Iron Alloy (25-12 Class), for High-Temperature Service

ABSTRACT
This specification covers iron-base, heat-resisting alloy castings, intended for structural elements, containers, and supports in electric furnaces, petroleum still tube supports, and for similar applications. The alloys shall be electric-furnace processed and heat treated. The castings shall conform to the required chemical compositions of nickel, chromium, carbon, nitrogen, manganese, silicon, phosphorus, sulfur, and iron. The specimens shall undergo tension test after aging and short-time high-temperature tension test and shall conform to the required values of tensile strength and elongation. A stress-rupture test shall also be performed wherein the specimens shall conform to the required values of tensile stress. The specimen shall also conform to the required values of magnetic permeability.
SCOPE
1.1 This specification covers iron-base, heat-resisting alloy castings of the 25 % chromium, 12 % nickel class, intended for structural elements, containers, and supports in electric furnaces, petroleum still tube supports, and for similar applications up to 2000 °F [1095 °C].  
1.2 In the absence of significant proportions of elements other than those prescribed in Section 5, the two types of alloys covered by this specification may in general be distinguished as follows:  
1.2.1 Type I—Alloys characterized by relatively low limiting creep stress at temperatures between 1500 and 2000 °F [815 and 1095 °C], and relatively high ductility at ordinary temperatures after aging for short periods at temperatures between 1300 and 1500 °F [705 and 815 °C].  
1.2.2 Type II—Alloys having relatively high limiting creep stress but which may develop low ductility at ordinary temperatures when aged for short periods at temperatures between 1350 and 1500 °F [730 and 815 °C].  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.  
1.3.1 Within the text, the SI units are shown in brackets.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
