ASME SA 387 Grade 11 Class 1/2 is a chromium-molybdenum alloy steel that contains about 1.25% chromium and 0.5% molybdenum, along with carefully controlled amounts of carbon (0.05–0.20%), manganese (0.40–0.70%), silicon, phosphorus, and sulfur. This unique blend enhances its strength, oxidation resistance, and creep resistance at high temperatures. The mechanical properties include a tensile strength ranging from 415 to 585 MPa and a yield strength of around 205 MPa. This material is known for its good weldability and long-lasting performance under thermal and mechanical stress, making it a great choice for high-temperature pressure vessels and boiler applications in demanding industrial settings.
