The **SA537 Class 2 Boiler Sheets and Plates** are primarily made from carbon, manganese, phosphorus, sulfur, and silicon. This type of pressure vessel quality steel undergoes heat treatment through normalization and tempering, which significantly boosts its strength and toughness. It boasts a **minimum yield strength of about 485 MPa** and impressive tensile strength that ranges from 620 to 690 MPa. These plates are known for their excellent impact resistance, stability at high temperatures, and superb weldability, making them ideal for constructing robust and safe pressure vessels and boiler components in challenging conditions.
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.
