ASTM A516 steel equivalent

 ASTM A516 steel equivalent

A516 steel is often used to make middle or low temperature pressure vessels. In ASTM A516/ A516M technical standard, the A516 steel is divided into four grades or levels: A516 GR 55 (380), A516 GR 60 (415), A516 GR 65 (450), A516 GR 70 (485).
