Luke Steel is a reputable manufacturer and supplier of ASME SA 387 Grade 9 Class 1/2 Sheets and Plates, based in Houston, USA. We take pride in providing high-performance alloy steel products that are specifically designed for high-temperature and high-pressure applications. Our SA 387 Gr 9 Class 1 and Class 2 plates are crafted with meticulous attention to ASME standards, making them perfect for use in boilers, pressure vessels, and heat exchangers. With a solid reputation for quality, precision, and dependable delivery, Luke Steel serves clients in the energy, petrochemical, and power generation sectors, both domestically and internationally.
The ASME SA 387 Grade 9 Class 1/2 Sheets and Plates are made up of chromium (9%) and molybdenum (1%) as the main alloying elements, along with carefully controlled levels of carbon, manganese, phosphorus, sulfur, and silicon. This specific alloy composition boosts resistance to heat, oxidation, and corrosion. The mechanical properties include a minimum tensile strength of 515 MPa for Class 1 and 585 MPa for Class 2, with minimum yield strengths of 275 MPa and 325 MPa, respectively. These plates excel in high-pressure, high-temperature environments and are recognized for their outstanding weldability, toughness, and long-lasting durability.
