Nestled in the industrial heart of Manila, Diaz Sheetsandplates has built a solid reputation as a trusted partner for high-grade steel. We specialize in supplying SA537 Class 2 Boiler Sheet and Plate, a material chosen by engineers and fabricators who cannot compromise on safety or durability. We understand that your projects demand reliability, which is why we focus on providing this premium steel, backed by a commitment to quality and service that has become our hallmark in the Philippines.
When you’re working with SA537 Class 2, you’re handling a resilient pressure vessel steel. Its composition, which includes carbon, manganese, and silicon, is carefully balanced to provide excellent strength and toughness. This translates into outstanding mechanical properties, including high tensile strength and a solid yield point, even under intense pressure and heat, ensuring your critical structures can withstand demanding conditions safely.
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.
Process of Manufacturing : Hot-Rolled (HR)

SA537 Class 2 boiler sheet and plate offer excellent strength and durability, making them ideal for pressure vessels and boiler applications. They are heat-treated to improve their hardness, ensuring resistance to high-pressure environments and elevated temperatures. The material demonstrates excellent weldability, enabling easy fabrication into complex shapes. Its resistance to corrosion and cracking under stress makes it suitable for harsh industrial environments. Additionally, SA537 Class 2 provides good toughness and impact resistance, ensuring long-term reliability in demanding applications such as power plants and chemical processing.
This plate is the unsung hero in demanding environments. Its primary role is in the construction of pressure vessels and boilers for power plants, chemical processing facilities, and oil refineries. You’ll also find it forming the core of large storage tanks and structural components where superior strength under stress is non-negotiable. Essentially, wherever safety and reliability are dictated by extreme pressure, this material delivers unwavering performance year after year.
