China ASTM A515 supplier

ASTM A 515 covers steel plates of intermediate tensile strength for pressure vessels to be operated at intermediate or higher temperatures. ASTM A515 have the four grades GR55,GR60, GR65, GR70. We offer excellent combinations of strength, weldability and toughness to permit designers flexibility in the design of pressure vessels coming under the jurisdiction of the ASME Pressure Vessel Code.
The plates are produced from fully killed steels and may be ordered to have an austenitic grain size from 1 to 5 for improved creep resistance and added resistance to graphitization at elevated temperatures. This material cannot be expected to provide adequate notch toughness, even in the normalized condition, to perform satisfactorily on low temperature pressure vessels.

ASTM A 515 plates can be gas cut using good shop or field practices. Plates over 0.30% carbon content and over 1 inch in thickness may display some edge hardening; if this is a problem, preheat to 200°F is suggested. Cutting of this material should not normally be carried out at a metal temperature below 50°F.
