ASTM WK78116

Revision of A336/A336M-21 Standard Specification for Alloy Steel Forgings for Pressure and High-Temperature Parts


ASME had previously requested the inclusion of Grade 91 Type 2 in ASTM specs. As part of ASME Code Case 2864-2, there is a requirement to include a minimum cooling rate from the austenitize. ASME has asked ASTM to include it in their standards so they can adopt it without change. This revision is to include the cooling rate.
