Nial Sheets and Plates is a reputable manufacturer and supplier of SA537 Class 2 Boiler Sheets and Plates based in Houston, USA. They’ve built a solid reputation for providing top-notch carbon-manganese-silicon steel plates specifically designed for pressure vessel and boiler applications. Nial caters to industries that require dependable performance in high-pressure and high-temperature environments. With a strong commitment to ASME standards, meticulous fabrication, and timely delivery, the company offers SA537 Class 2 Sheets and Plates that prioritize safety and durability. Nial Sheets and Plates plays a vital role in essential sectors like oil and gas, petrochemical, and power generation by delivering reliable boiler-quality steel solutions.
SA537 Class 2 Boiler Sheets and Plates are crafted from carbon-manganese-silicon steel, tailored for pressure vessel applications. These plates typically feature around 0.24% carbon, 1.10–1.50% manganese, and 0.13–0.45% silicon, with minimal phosphorus and sulfur content to boost weldability and toughness. They boast impressive tensile strength ranging from 485–620 MPa and a minimum yield strength of about 345 MPa. Heat treatment through normalizing and quenching or tempering enhances their impact resistance, toughness, and durability, making them ideal for pressure vessels that operate under elevated pressures.
Grade : ASME SA 537 CL.2 Boiler and Pressure Vessel Steel Plates
Width : 1000mm-4500mm
Thickness : 5mm-150mm
Length : 3000mm-18000mm
