Minimum Hardness according to NACE and API 6A
Minimum Hardness according to NACE and API 6A
(OP)
The maximum hardness according to NACE and API 6A is 250 HV. I can't find the requirements for minimum hardness in these standards. What is the minimum requirements? (It is PWHT)

API doesn't get into hardness for austenitics, but you should be able to find them in an ASTM spec. try ASTM A182 for forgings.
The bottom line is that hardness is a direct representative of the tensile strength of the material.
