ASTM A515 GR65 pressure vessel steel

ASTM A515 GR65 pressure vessel steel

ASTM A515 GR65 is a kind of steel plates material used to fabric middle or high temperature pressure vessels. ASTM A515 has three levels : A515 Grade 415, A515 Grade 450, A515 Grade 485. A515 GR 65 under the standard of ASTM A515/A515M is for high temperature pressure vessels.

A515 GR 65 steel plate with good impact resistance, low temperature deformation, good welding performance, good anti-fatigue performance, good anti-crack properties, micro-alloying, high purity.

Standard: ASTM A515/A515M
Dimension range : 3mm -500mm * 1000mm-4000mm * 1000mm-18000mm
