ASTM A537 Class 1 plates are supplied in the normalized 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.
ASTM A537 Class 1 carbon steel plates are engineered to be used in pressure vessel applications.
The material is a normalized 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 BEBON INTERNATIONAL Limited supplies
A537 Class 1 plates to the world's leading fabricators who in turn serve the Oil, Gas and
Petrochemical industry.

STM A537 Class 2 and class 3 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.
