From the heart of Amman, Jordan, Nizar Sheetsandplates has built a reputation as a trusted partner in the industrial supply chain. We take pride in furnishing high-grade materials like the SA537 Class 2 Boiler Sheet and Plate, understanding the critical nature of such components. Our commitment goes beyond mere supply; it’s about providing reliability and assurance to the industries that form the backbone of our region’s infrastructure, ensuring every project begins with a foundation of unwavering quality and trusted performance.
The composition of SA537 Class 2 is primarily carbon-manganese-silicon, carefully balanced to deliver excellent strength and toughness. This specific grade is heat-treated to achieve its notable mechanical properties, including a high yield strength that allows it to withstand immense pressure. It also maintains good notch toughness, even in lower temperature service environments, which is a crucial factor for its durability and long-term performance in demanding applications.
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 essential for constructing critical pressure vessels found in power generation plants, petrochemical facilities, and other industrial settings. Its primary use is in the fabrication of boilers and storage tanks that must operate safely under high-pressure conditions. Because of its reliable performance, engineers also specify it for structural components in large machinery and mining equipment, where its combination of strength and impact resistance ensures safety and longevity in some of the most challenging work environments.
