ASTM A537 & ASME SA537 Carbon-Manganese-Silicon Steel for Pressure Vessel Plates
The ASTM A537 specification covers heat treated carbon steel plates for pressure vessel applications.
ASTM A537 Class 1 plates are supplied in the normalised condition whilst Class 2 plates are quenched and tempered. ASTM A537 carbon steel plates promote greater tensile and yield strength than pressure vessel plates supplied under the ASTM A516 standard.
We also have own own steel processing plant which means that we can supply ASTM A537 steel profiles cut to your specific requirements using our CAD controlled multi–head flame cutters.
ASTM A537 Class 1
ASTM A537 Class 1 carbon steel plates are engineered to be used in pressure vessel applications.
The material is a normalised steel which is heat treated and as a consequence displays greater yield and tensile strength than the more standard ASTM A516 grades. The steel is ideal for use in pressurised service both in boilers and pressure vessels.
We can supply ASTM A537 Class 1 plates from stock or directly from the mill. We also offer an in house profiling service where the material can be cut to the size or shape you require.

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.
