These plates are specifically designed for high-pressure applications and are crafted using cutting-edge processes to comply with ASME standards. The SA537 Class 1 plates from Wiraphan are renowned for their exceptional toughness, strength, and weldability, making them perfect for fabricating boilers and pressure vessels. With a reputation for consistent quality and timely delivery, Wiraphan caters to vital industries like oil & gas, petrochemical, and power generation, providing dependable steel solutions.
The SA537 Class 1 Boiler Sheets and Plates are produced from carbon-manganese-silicon steel and come in a normalized condition. Their typical chemical makeup includes Carbon (≤0.24%), Manganese (0.7–1.6%), and Silicon (0.13–0.45%), along with minimal amounts of Phosphorus and Sulfur (≤0.035%). On the mechanical side, SA537 Class 1 boasts a minimum yield strength of 345 MPa and a tensile strength ranging from 485 to 620 MPa. These plates are known for their excellent notch toughness, making them suitable for applications that require moderate to high pressure and good weldability.
Grade : ASME SA 537 CL.1 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.
