A516 grade 65 steel plates ASTM A516 pressure vessel steel plate grades

The ASTM A516 standard covers multiple grades such as 60, 65, 70, etc. A516 grade 65 is known for its balanced strength and plasticity. Optimized carbon manganese composition, combined with normalizing treatment, A516 grade 65 steel can maintain high impact toughness at low temperatures of -30 ℃, suitable for the needs of medium and low pressure vessels.

A516 grade 65 steel plate has good formability and weldability, and is widely used in liquefied gas storage tanks, boiler shells, and chemical equipment. Strict non-metallic inclusion control and non-destructive testing requirements ensure long-term pressure stability and crack propagation resistance.

As the mainstream material for pressure vessels worldwide, A516 grade 65 achieves precise matching of high strength and safety redundancy through standardized production and quality traceability system, helping industrial equipment operate efficiently and reliably.
