Operating from the industrial heart of Amman, Jordan, Nizar Sheetsandplates has built a reputation for supplying high-grade materials to demanding sectors. We are proud to be a trusted source for SA537 Class 1 Boiler Sheet and Plate, a material chosen for its exceptional reliability. Our clients rely on us not just for the product itself, but for our deep understanding of the stringent requirements it must meet in critical applications, ensuring their projects are built on a foundation of integrity and strength.
The composition of SA537 Class 1 leans on a carbon-manganese blend, often with fine grain practice for added toughness. It achieves a minimum yield strength of 50 ksi (345 MPa), offering a robust resistance to pressure and stress. This excellent strength is complemented by good weldability and notch toughness, even at lower temperatures. These properties make it a dependable choice for engineers who need a plate that can handle significant internal forces without compromising on performance.
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.
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)

We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
SA537 Class 1 Boiler Sheet and Plate offer excellent strength, toughness, and resistance to pressure, making them ideal for use in high-temperature and high-pressure applications like boilers and pressure vessels. Their superior weldability allows for easy fabrication, while their resistance to cracking and corrosion enhances reliability in demanding environments. This steel is heat-treated to ensure improved mechanical properties, long-term durability, and performance. With excellent formability and impact resistance, SA537 Class 1 is a trusted choice for power generation, petrochemicals, and manufacturing industries.
The primary use for this plate is, as the name suggests, in the construction of boilers and pressure vessels that operate at moderate to lower temperatures. You will find it in power generation facilities, petrochemical plants, and large industrial heating systems. Its balanced properties also make it suitable for other heavy fabrication projects where a combination of high strength and good weldability is essential, providing a durable and safe material for structures that are designed to last for decades.
