ASTM A622GR.A,B,C steel Mechanical Properties
A622GR.A,B,C this material is mainly used to fabricate boiler and pressure vessel. So ,same the other boiler and pressure vessel using steel plate, this kind of steel has the good grain and Mechanical properties. It's yield strength is between 295- 355 MPa (there is different min strength point at the different thickness.) A622GR.A,B,C tensile strength is from 450MPa to 630MPa. (different min strength point at the different thickness.) More detailed information about ASTM A622GR.A,B,C steel Mechanical Properties , please refer to the following table:
