ASTM A247-24(Test Method)
Standard Test Method for Visual Evaluation of Graphite in Iron Castings

SIGNIFICANCE AND USE
4.1 The comparison of observed graphite particles with the structures shown in the charts give only purely descriptive information on the type, distribution, and size of the graphite in the sample being evaluated. It does not indicate, except in a very broad way, the origin of the graphite or the suitability of the iron-carbon alloy for a particular service.
SCOPE
1.1 This test method covers the classification of graphite in cast irons in terms of type, distribution, and size by visual comparison to reference photomicrographs. This test method is intended to be applicable for all iron-carbon alloys containing graphite particles, and may be applied to gray irons, malleable irons, compacted graphite irons, and the ductile (nodular) irons.  
1.2 The reference photomicrographs included in this test method are in no way to be construed as specifications. In an appropriate specification for a specific material where graphite microstructure is an important consideration, this test method may be used as a reference to concisely define the graphite microstructure required.  
1.3 These reference photomicrographs are offered primarily to permit accurate reporting of microstructures of cast irons and to facilitate the comparison of reports by different laboratories or investigators.  
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.5 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.  
1.6 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 A823-99(2023)(Specification)
Standard Specification for Statically Cast Permanent Mold Gray Iron Castings

ABSTRACT
This specification covers gray iron castings that are statically cast in permanent molds. Castings under this specification are classified into a number of grades (A-SA, A-SB, A-SC, A-SS, A-CA, A-CB, A-CC, N-SA, N-SB, N-SC,N-SS, N-CA, N-CB and N-CC) based on the properties of separately cast test bars. The grades are designated A for annealed or N for normalized; followed by an S or a C to designate a solid or a cored casting; followed by an A, B, C, or S to designate the test bar to be poured with the castings. The cast test bar shall be selected on the basis of the controlling section size of the casting and shall have the specified dimensions (diameter and length). Castings may be produced in the as cast state provided the tensile strength and Brinell hardness requirements are met. The chemical composition and heat treatment shall be such as to produce these mechanical requirements as well. A suitable permanent mold design for separately cast test bars is described and the tension test requirements are detailed.
SCOPE
1.1 This specification covers gray iron castings that are statically cast in permanent molds.  
1.2 No precise quantitative relationship can be stated between the properties of the iron in various locations of the same casting or between the properties of a casting and those of a test specimen cast from the same iron (see Appendix X1).  
1.3 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.  
1.4 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.

The following conditions for casting will be supplied: as-cast, as-cast and stress relieved, hardened, hardened and stress relieved, or softened for machining. Heat treatment shall be done. The chemical composition of a class and type (that is, Class I, Type A) shall conform to the range of values specified for carbon, manganese, silicon, nickel, chromium, molybdenum, copper, phosphorus, and sulfur. Hardness test shall also be made.
SCOPE
1.1 This specification covers a group of white cast irons that have been alloyed to secure high resistance to abrasive wear in the applications of the mining, milling, earth-handling, and manufacturing industries.  
1.2 Simple and low-alloy white cast irons that consist essentially of iron carbides and pearlite are specifically excluded from this specification.  
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.

Standard Specification for Austempered Ductile Iron Castings

ABSTRACT
This specification covers ductile iron castings that are subsequently heat treated by an austempering process. The chemical composition requirements may be agreed upon between the manufacturer, heat treater, and the purchaser. Requirements for the microstructure constituents such as graphite, ausferrite (acicular ferrite and high carbon, stable austenite), pearlite, and martensite are prescribed. The iron shall conform to the mechanical property requirements including tensile strength, yield strength, elongation, impact energy, and Brinell hardness. Castings shall be heat treated by an austempering process detailed in this specification. The standard specimens for tension and Charpy impact tests are illustrated.
SCOPE
1.1 This specification covers ductile iron castings that are subsequently heat treated by an austempering process as defined in 9.1.  
1.2 The application of the austempering heat treatment extends the range of properties achievable in ductile iron castings.  
1.3 No precise quantitative relationship can be stated between the properties of the iron in various locations of the same casting or between the properties of castings and those of a test specimen cast from the same iron (see Appendix X1). However, austempering heat treatment will tend to diminish any differences in mechanical properties.  
1.4 The production of castings, machining (if required), and the austempering heat treatments may be performed by different manufacturers, as covered in Section 13. The purchaser should establish by contract agreement, at the time of ordering, the responsibility of the various parties for meeting the specification requirements.  
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 Exception—Within the text, the SI units are shown in brackets.  
1.6 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.

Standard Specification for Corrosion-Resistant High-Silicon Iron Castings

ABSTRACT
This specification covers standards for high-silicon iron castings of Grades 1, 2, and 3 intended for severe environment corrosion-resistant services. The alloy shall be produced by any melting and casting process, or combination of processes that will be capable of meeting the specified contents of carbon, manganese, silicon, chromium, molybdenum, and copper. Reference analysis methods are given for each chemical component. Transverse bend test and hydrostatic test shall be performed. Material shall conform to minimum load at center and minimum deflection at center requirements.
SCOPE
1.1 This specification covers high-silicon cast iron castings intended for corrosion-resistant service.  
1.2 This specification covers three grades as shown in Table 1. Selection of grade depends on the corrosive service to be experienced by the casting. All three grades are suited for application in severe corrosive environments. However, Grade 2 is particularly suited for application in strong chloride environments, and Grade 3 is recommended for impressed current anodes.    
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 The following safety hazards caveat pertains only to the test method portion, Section 9, of this specification: 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.
