FAQs
What’s the difference between B7 and B7M?
B7M is tempered differently to reduce hardness for sour-service environments.
Do B7 studs require MTRs?
Yes, MTRs confirm heat treatment and chemistry, and ATP provides them with every order.
Can B7 be used in low temperatures?
B7 is optimized for elevated temperature service; B7M or L7 are recommended for cryogenic use.
