Daksh Sheets and Plates is a well-respected manufacturer and supplier based in Delhi, India, specializing in ASME SA 387 Grade 22 Class 1 & 2 Sheets and Plates. These alloy steel plates are engineered to withstand high temperatures and pressures, making them ideal for critical applications like pressure vessels and boilers. Grade 22, which is a chromium-molybdenum steel, boasts impressive strength, oxidation resistance, and thermal stability. Class 1 is known for its excellent formability and ductility, while Class 2 offers superior tensile strength. We provide these plates in various sizes, catering to industries such as power generation, oil refining, and chemical processing.
ASME SA 387 Grade 22 steel contains around 1.90–2.60% chromium and 0.87–1.13% molybdenum, along with carefully controlled levels of carbon, manganese, silicon, phosphorus, and sulfur. These elements work together to boost its oxidation resistance and enhance mechanical strength at high temperatures. Class 1 plates have a minimum yield strength of 275 MPa and a tensile strength ranging from 415 to 585 MPa, while Class 2 offers a higher yield strength of 310 MPa and tensile strength between 450 and 620 MPa. Both classes undergo normalization and tempering to improve creep resistance and durability during continuous thermal and pressure cycling.
