Alloy Steel Plates, Sheets, and Coils are high-strength flat steel products engineered for high-temperature, high-pressure, and corrosive service conditions. These materials are alloyed with chromium and molybdenum to improve strength, oxidation resistance, and creep performance.
Alloy Steel Plates and Coils are widely used in power plants, refineries, petrochemical units, boilers, and pressure vessel fabrication where durability and reliability are critical.
Alloy Steel Plates, Sheets, and Coils are manufactured as per ASTM and ASME standards. Commonly supplied grades include Alloy Steel Gr 5, Gr 9, Gr 11, Gr 12, and Gr 22, offering excellent mechanical strength, heat resistance, and corrosion resistance for demanding industrial applications.
