The ASME SA 387 Grade 9 Class 1 & 2 Sheets and Plates are made up of chromium (8–10%) and molybdenum (0.90–1.10%) as their primary alloying elements, along with carbon, manganese, phosphorus, sulfur, and silicon. These plates are specifically designed for high-temperature service, offering impressive resistance to thermal stress and oxidation. While Class 1 has a slightly lower tensile strength range (415–585 MPa), Class 2 boasts higher strength (450–620 MPa), yet both classes provide excellent weldability and creep resistance.
