ASTM A537 Class 1 carbon steel plates are built for use in pressure vessel applications.
Applications of ASTM A537 Class 1 Carbon Steel Plate
The material is a normalized steel which is heat treated and as a consequence exhibits greater yield and tensile strength than the more standard ASTM A516 grades. The steel is suitable for use in pressurized service both in pressure vessels and boilers, and Pressure Vessel Steels supplies A537 Class 1 plates to the world's top fabricators who in turn serve the oil, gas, and petrochemical industry.
