ASME SA 387 Grade 11 Class 1/2 Sheet and Plates are specialized alloy steel products that mainly consist of chromium (1.00–1.50%) and molybdenum (0.45–0.65%). These elements work together to boost high-temperature strength and corrosion resistance. The carbon content is between 0.05–0.15%, and you’ll also find some manganese, phosphorus, sulfur, and silicon in the mix. These plates are known for their impressive mechanical properties, boasting a tensile strength of 415–585 MPa and a minimum yield strength of 205 MPa for Class 1, while Class 2 offers a bit more strength. They’re also great for welding, have good thermal stability, and resist creep, making them perfect for use in pressure vessels and boilers.
Industries that require materials capable of withstanding high temperatures and pressures, like petrochemical, oil and gas, and power generation, frequently use ASME SA 387 Grade 11 Class 1/2 Sheet and Plates. These plates are particularly well-suited for crafting heat exchangers, reactors, and pressure vessels thanks to their excellent thermal stability and resistance to oxidation and corrosion. Class 1 is generally used in moderate temperature settings, while Class 2 is designed for higher temperature applications, providing enhanced strength. Their durability under mechanical stress makes them a go-to choice in refineries, steam pipelines, and boilers, ensuring safety and longevity even in tough environments.
