ASME SA 387 Grade 91 Class 1/2 Sheets and Plates are made from chromium-molybdenum-vanadium alloy steels, typically featuring 9% chromium and 1% molybdenum, along with vanadium and niobium. This unique composition provides excellent creep strength, oxidation resistance, and thermal stability. Class 1 plates offer a tensile strength ranging from 585 to 760 MPa and a yield strength of 415 MPa, while Class 2 plates boast even higher mechanical properties for more demanding applications. These plates are known for their outstanding toughness, weldability, and long-lasting performance at high temperatures. Their carefully balanced chemical and mechanical properties make them perfect for heavy-duty pressure vessels, boilers, and critical components that operate in elevated temperature environments.
ASME SA 387 Grade 91 Class 1/2 Sheets and Plates find extensive use in industries that require materials capable of withstanding extreme heat and pressure. They are particularly popular in power generation plants, especially in boilers, steam turbines, and heat exchangers, thanks to their excellent creep resistance and strength. The petrochemical and oil and gas sectors also rely on these plates for pressure vessels, reactors, and high-temperature pipelines. Their ability to resist thermal stress and oxidation makes them ideal for refineries and chemical plants. With a long service life, durability, and reliability, these plates are a go-to choice for demanding applications.
