ASTM A537 Class 1 Steel for Pressure Vessels

ASTM A537 Class 1 steel ( A537CL1) is a kind of carbon-manganese-silicon steel for pressure vessel plates. As for heat treatment, A537 Class 1 plate shall be normalized. A537 Class 1 steel plate is a higher yield and tensile strength material used in the fabrication of pressurised vessels and steel boilers

ASTM A537 Class 1 Steel Plates Features

Heat-treated pressure vessel quality steel plate to increase yield and tensile strength, especially when compared to A516 grades.
Available in three classes: 1, 2 and 3.
Classes 2 and 3 are quenched and tempered, whereas class 1 is normalized.
Ideal for boilers and pressure vessels.
Used in the oil, gas and petrochemical industry.

ASTM A537 Class 1 Pressure Vessel Plate Specification :

Width: 1000mm-4500mm
Thickness: 5mm-150mm
Length: 3000mm-18000mm
Supply Condition : As Rolled, Normalized Rolling, Furnace Normalizing, Vacuum Degassing, Simulated Post-Weld Heat Treatment or as per customer requirement.
Impact tested : -52° C
Tempering: Notch toughness can be improved by quenched cooling from hot rolling or normalizing by the supplier. If such a faster cooling rate is agreed upon between purchaser and supplier then the steel is also to be tempered at 1200 F.
Applications : Used for Boilers and Pressure Vessels Application.
Process of Manufacturing : Hot-Rolled (HR)
ASTM A537 Class 1 pressure vessel plates are engineered to be used in pressure vessel applications. 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 1 is a material used extensively by the oil, gas and petrochemical industry.
