ASTM WK86416

Revision of A193/A193M-23 Standard Specification for Alloy-Steel and Stainless Steel Bolting for High Temperature or High Pressure Service and Other Special Purpose Applications


API has a maximum hardness of 34 HRC for some critical applications of Grades B7. API has requested that ASTM address this requirement. It is not practical to lower the hardness for all applications. However, it does reasonable to add a supplemental requirement to add a supplemental to handle the API request.
