PRODUCT DETAILS
Product introduction
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 offer material to the ASTM A537 specification in a number of sizes and thicknesses to suit your requirements.
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 and we supplies A537 Class 1 plates to the world’s leading fabricators who in turn serve the Oil, Gas and Petrochemical industry.
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.
