ASTM WK71880

Revision of A781/A781M-18c Standard Specification for Castings, Steel and Alloy, Common Requirements, for General Industrial Use

Keywords

None Provided

Rationale

Ballot 1: Add a note to Terminology: A941 controlling cross section thickness (Tc) was added for forgings and shall not apply to castings, which provide complex shapes including internal geometry (rationale is both the challenge in determining a Tc for casting and who shall be responsible for it; also casting standards already use casting ruling section T). Ballot 2: Change CGMMN to CG6MMnN to be consistent with alloy designations (X1). Ballot 3: Update mechanical testing: a. For consistency and conciseness, revise mechanical testing and charpy testing.
