ASTMA387Grade12Class1

ASTM A387 Grade 12 is in the standard ASTM A-387. A387 Grade 12 is a kind of Cr-Mo-alloy steel material used to fabric high temperature pressure vessels. Because of the good mech For pressure vessel steel plate SA387 Grade 12 CL 1, the tensile strength shall be within 380 to 550, minimum yield strength is 230 Mpa.anical property, A387GR12 is widely used in the high temperature vessels industry.
