ASTM A537 Class 1 ,ASTM A537 Class 2
Specification: ASTM A537
Our Grades: ASTM A537 Class 1/ ASTM A537 Class2 carbon steel plates
ASTM A537 Class 1 carbon steel plates are engineered to be used in pressure vessel applications.
ASTM A537 Class 1 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 pressured service both in boilers and pressure vessels and Shanghai Katalor Industry Co., Ltd supplies A537 Class 1 plates to the world's leading fabricators who in turn serve the Oil, Gas and Petrochemical industry.
ASTM A537 Class 2 steel is a higher yield and tensile strength material used in the fabrication of pressured 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 can supply ASTM A537 Class 1/Class2 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.
