SA537 Class 2 is a carbon-manganese steel type used in high-pressure vessel applications. Its chemical composition is usually carbon (0.20-0.25%), manganese (0.60-0.90%), phosphorus (max 0.025%), sulfur (max 0.025%), and silicon (0.20-0.35%). It has very good mechanical properties like minimum tensile strength of 585 MPa, yield strength of 380 MPa, and elongation of about 22%. The steel is good in toughness, weldability, and heat resistance, and it is suitable for heavy-duty boiler and pressure vessel fabrication.
Grade : ASME SA 537 CL.2 Boiler and Pressure Vessel Steel Plates
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.
