ASTM A537 Class 2 Pressure Vessel Steel Plate

ASTM A537 Class 2

ASTM A537 Class 2 steel is a higher yield and tensile strength material used in the fabrication of pressurised vessels and steel boilers.

The steel includes the alloying of carbon, manganese and silicon and is heat treated using the quenched and tempered method which gives the material its residual strength. Sourced by the world’s leading fabricators, ASTM A537 Class 2 is a material used extensively by the oil, gas and petrochemical industry.

We will supply ASTM A537 Class 2 plates from stock or directly from the mill. We also offer steel cutting services including CAD based flame cutting to cut your steel into particular shapes.

Pressure vessel and boiler quality steel are commonly found throughout the oil industry (including inshore and offshore), the petrochemical industry and the gas production industry. The companies in these industries set the highest demands in terms of quality, testing and conditions of supply, and we have all the necessary expertise to meet these demands.

In recognition of the increasing need for pressure vessel steel plate to demonstrate HIC Resistant properties we also available ex–stock. We are particularly suited for pressure equipment where wet H2S corrosion can be a problem.
