ASME SA 387 Grade 12 Class 1/2 Sheets and Plates consist of alloy steel mainly consisting of about 1.00% chromium and 0.50% molybdenum. These components offer excellent high-temperature strength, corrosion resistance, and structural integrity. Other components are carbon, manganese, silicon, phosphorus, and sulfur—accurately balanced for the best performance. Class 2 has better mechanical properties than Class 1, with a tensile strength of at least 485 MPa. These plates are heat-treated for added durability and can be utilized in applications with high thermal and mechanical stress, while possessing good weldability.
