ASTM A1010/A1010M-24(Specification)
Standard Specification for Higher-Strength Martensitic Stainless Steel Plate, Sheet, and Strip

ABSTRACT
This specification covers the standard for martensitic stainless steel for various structural, architectural, pressure vessel, and heat-resisting applications. The material shall undergo heat-treatment by tempering. The steel shall conform to the requirements as to chemical composition specified for carbon, manganese, phosphorus, sulfur, silicon, chromium, nickel, molybdenum, and nitrogen. Mechanical testing shall be performed on the steel and shall conform to the specified values in mechanical properties such as yield strength, tensile strength, elongation, and Brinell hardness.
SCOPE
1.1 This specification covers martensitic stainless steels for various structural, architectural, pressure vessel, and heat-resisting applications. The mechanical properties of these steels are customarily, but not necessarily, developed by a suitable heat treatment generally referred to as tempering.  
1.2 Steel products under this specification are available in two grades:
Grade  
Yield Strength, min, ksi [MPa]  
40 [275]  
40 [275]  
50 [345]  
50 [345]  
1.3 The maximum thickness of plates is limited only by the capacity of the composition to meet the specified mechanical property requirements; however, current practice normally limits the maximum thickness of plates furnished under this specification to 2 in. [50 mm].  
1.4 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. The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. 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 non-conformance with the standard.  
1.5 Supplementary requirements 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.  
1.6 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 A370-24(Test Method)
Standard Test Methods and Definitions for Mechanical Testing of Steel Products

SIGNIFICANCE AND USE
4.1 The primary use of these test methods is testing to determine the specified mechanical properties of steel, stainless steel, and related alloy products for the evaluation of conformance of such products to a material specification under the jurisdiction of ASTM Committee A01 and its subcommittees as designated by a purchaser in a purchase order or contract.  
4.1.1 These test methods may be and are used by other ASTM Committees and other standards writing bodies for the purpose of conformance testing.  
4.1.2 The material condition at the time of testing, sampling frequency, specimen location and orientation, reporting requirements, and other test parameters are contained in the pertinent material specification or in a general requirement specification for the particular product form.  
4.1.3 Some material specifications require the use of additional test methods not described herein; in such cases, the required test method is described in that material specification or by reference to another appropriate test method standard.  
4.2 These test methods are also suitable to be used for testing of steel, stainless steel and related alloy materials for other purposes, such as incoming material acceptance testing by the purchaser or evaluation of components after service exposure.  
4.2.1 As with any mechanical testing, deviations from either specification limits or expected as-manufactured properties can occur for valid reasons besides deficiency of the original as-fabricated product. These reasons include, but are not limited to: subsequent service degradation from environmental exposure (for example, temperature, corrosion); static or cyclic service stress effects, mechanically-induced damage, material inhomogeneity, anisotropic structure, natural aging of select alloys, further processing not included in the specification, sampling limitations, and measuring equipment calibration uncertainty. There is statistical variation in all aspects of mechanical testin...
SCOPE
1.1 These test methods2 cover procedures and definitions for the mechanical testing of steels, stainless steels, and related alloys. The various mechanical tests herein described are used to determine properties required in the product specifications. Variations in testing methods are to be avoided, and standard methods of testing are to be followed to obtain reproducible and comparable results. In those cases in which the testing requirements for certain products are unique or at variance with these general procedures, the product specification testing requirements shall control.  
1.2 The following mechanical tests are described:

Standard Practice for Hot Isostatic Pressing of Steel, Stainless Steel, and Related Alloy Castings

ABSTRACT
This practice covers general requirements for Hot Isostatic Pressing (HIP) of steel, stainless steel, and related alloy castings. HIP is a solid state process which applies heat and pressure simultaneously to objects in an autoclave via an inert gas in such a way as to eliminate internal voids and obtain desired properties. Inert gas is a non-oxidizing gas used for pressurizing a HIP vessel. This practice deals with quality requirements, autoclave type/qualification, temperature uniformity, temperature measurement and control, pressure measurement and control, and gas measurement.
SCOPE
1.1 This practice covers general requirements for hot isostatic pressing (HIP) of steel, stainless steel, and related alloy castings.  
1.2 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.  
1.3 Units—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 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.  
1.5 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 A1040-17(2022)(Guide)
Standard Guide for Specifying Harmonized Standard Grade Compositions for Wrought Carbon, Low-Alloy, and Alloy Steels

SIGNIFICANCE AND USE
4.1 It is anticipated that the ASTM Subcommittees A01.02, A01.03, A01.06, A01.09, A01.11, A01.15, A01.19, A01.22, and A01.28 will use the standard composition limits listed in this guide for the grades identified in their product specifications unless there is a specific technical justification for doing otherwise.  
4.2 The composition limits given in this guide are to be used as guides in determining limits for each of the elements included in the total composition of each grade. The composition limits have been established with the intent that each ASTM subcommittee will find it necessary to require only a minimum number of changes to reflect specific technical effects. Section 5 lists the general guidelines followed for determining the limits for each element; the limits established in this guide are based upon these guidelines.
SCOPE
1.1 This guide covers ASTM Subcommittees A01.02, A01.03, A01.06, A01.09, A01.11, A01.15, A01.19, A01.22, and A01.28 for specifying chemical composition limits of wrought carbon, low-alloy, and alloy steels. It is intended that these recommended grade composition limits be suitable for adoption by other standardization bodies that prepare standards for carbon, low-alloy, and alloy steel products, including discontinued steels.  
1.2 Included in this guide are the recommendations for determining the number of significant figures for specifying chemical composition.  
1.3 The carbon and alloy steel grades in all standards overseen by the aforementioned ASTM subcommittees have been included, except those grades applicable to restricted special end uses.  
1.4 Not addressed are minor composition modifications that a specific ASTM subcommittee may find necessary to accommodate effects of normal processing or to enhance fabricability by the producer or user, or both.  
1.5 Also not generally addressed (except where established by ASTM subcommittees) is a complete rationalization of all limits, especially where such would conflict with long-standing practices and is not justified by special technical effect.  
1.6 This guide does not address discontinued or formerly standard steel grades. A listing of such steel grades can be found in SAE J1249. Also excluded from this guide are cast materials and welding filler metals.  
1.7 In 1995, the AISI made the decision to transfer the responsibility of maintaining its numbering system to the Society of Automotive Engineers (SAE) for carbon and alloy steels (SAE J403 and SAE J404) and to ASTM International for stainless steels (Guide A959 and others). To inform users of this important event, historical information is included in the appendix of this standard.  
1.8 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.9 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.
