The SA537 Class 2 Boiler Sheets and Plates are constructed from quenched and tempered carbon-manganese-silicon steel. This particular grade boasts impressive mechanical properties, featuring a minimum yield strength of 485 MPa and a tensile strength that ranges from 620 to 795 MPa. The steel is known for its excellent notch toughness, making it suitable for high-pressure vessels and boilers that require superior strength. Additionally, it offers good weldability, allowing for fabrication processes like forming, cutting, and welding without sacrificing structural integrity under high stress and temperature.
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.
