Why are low temp steels used in ASTM?
These steels are made to a fine-grain practice. The ASTM requires for low temp steels better control of impurities, the steels are kileed, etc. And at the end of the day they are impact tested.See all results for this questionWhich is the best heat treatment for ASTM A36 steel?Heat Treatment. Any standard carburizing and hardening methods of AISI 1018 steel is suitable for ASTM A36. ASTM A36 is subjected to the following processes: Applications.
