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 9 is a chromium-molybdenum alloy steel that contains around 8.00–10.00% chromium and 0.90–1.10% molybdenum, along with carefully controlled amounts of carbon, manganese, silicon, sulfur, and phosphorus. This specific composition gives it remarkable resistance to high-temperature oxidation and creep. Class 1 plates are provided in a normalized state, while Class 2 plates undergo quenching and tempering to achieve greater strength. In terms of mechanical properties, these plates boast high tensile and yield strength, good toughness, and outstanding resistance to pressure at elevated temperatures.
ASME SA 387 Grade 9 Class 1 and Class 2 sheets and plates find extensive use in pressure vessels, boilers, and heat exchangers that operate under high temperatures. They are commonly utilized in petrochemical plants, refineries, power generation facilities, and chemical processing industries. These plates are ideal for equipment that faces high pressure, thermal stress, and corrosive environments. Thanks to their exceptional creep resistance, strength, and long-term stability, SA 387 Grade 9 materials are the go-to choice for critical high-temperature and high-pressure industrial applications.
