Victor Sheets and Plates, a top-notch manufacturer and supplier based in Abuja, Nigeria, offers high-quality SA537 Class 1 Boiler Sheets and Plates that adhere to international standards for pressure vessel applications. These plates are crafted from carbon-manganese-silicon steel, specifically designed for moderate to high-pressure service, and are heat-treated (quenched and tempered) to enhance their strength and toughness. With outstanding weldability, impact resistance, and durability, SA537 Class 1 is perfect for boilers, pressure vessels, and heat exchangers in demanding industrial settings. Victor Sheets and Plates is committed to delivering consistent product quality, making these plates a trusted choice for the power, petrochemical, and energy industries.
SA537 Class 1 is composed of carbon (≤0.24%), manganese (0.60–1.60%), silicon (0.15–0.50%), phosphorus (≤0.025%), and sulfur (≤0.025%). The plates undergo a quenching and tempering process, resulting in an impressive blend of strength and ductility. They boast a tensile strength ranging from 485 to 620 MPa, a yield strength of about 345 MPa, and an elongation of at least 20%. These characteristics ensure exceptional impact toughness, weldability, and formability, even at moderate to high temperatures. The alloy’s well-balanced chemistry enables it to excel in pressure vessel and boiler applications where structural integrity and thermal stability are crucial.
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.
