ASTM WK86841

Revision of A681-08(2022) Standard Specification for Tool Steels Alloy


ASTM A681 does not currently permit product analysis tolerances from the heat analysis limits. Such product tolerances are permissible in many A01 specifications, e.g, A182, A788, A29, A6. The suggested tolerances in this ballot were developed based on consideration of the tolerances currently given in the following specifications: AMS 2248 (“Chemical Check Analysis Limits, Corrosion- and Heat-Resistant Steels and Alloys, Maraging and Other Highly Alloyed Steels, and Iron Alloys”) and A961 ( “Common Requirements for Steel Flanges, Forged Fittings, Valves, and Parts for Piping Applications,” which gives the product analysis tolerances for ASTM A182). The method of analysis and sampling were also updated to current practices.
