We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
ASME SA 387 Grade 22 is a chromium-molybdenum alloy steel that contains around 2.00–2.50% chromium and 0.90–1.10% molybdenum, along with carefully controlled levels of carbon, manganese, silicon, sulfur, and phosphorus. This specific composition delivers outstanding strength, creep resistance, and oxidation resistance at high temperatures. Class 1 plates are provided in a normalized state, while Class 2 plates undergo quenching and tempering to enhance their mechanical properties. These materials boast high tensile and yield strength, impressive toughness, and reliable performance under pressure.
ASME SA 387 Grade 22 Class 1 and Class 2 sheets and plates find extensive use in the construction of pressure vessels, boilers, reactors, and heat exchangers that operate under high temperatures and pressures. They are frequently utilized in oil refineries, petrochemical plants, power generation facilities, and chemical processing industries. These plates are ideal for components that face hydrogen service, thermal stress, and corrosive environments. Their remarkable mechanical strength, excellent weldability, and resistance to high-temperature degradation make them a top choice for critical industrial equipment.
