ASME SA 387 Grade 9 Class 1/2 Sheets and Plates are specially crafted chromium-molybdenum alloy steels designed to excel in high-temperature pressure applications where strength, creep resistance, and oxidation resistance are essential. Shalan Steel, a reputable manufacturer and supplier located in Kuala Lumpur, Malaysia, proudly provides top-quality SA 387 Gr 9 Cl 1 and Cl 2 plates to clients throughout Malaysia and Southeast Asia, perfect for thermal and pressure-based systems.
SA 387 Grade 9 features 2.25% chromium and 1% molybdenum, much like Grade 22, but tailored for specific high-temperature settings. Class 1 plates boast a tensile strength ranging from 415 to 585 MPa, while Class 2 offers a stronger range of 515 to 690 MPa, with both classes ensuring a minimum yield strength of 275 MPa. Typically, these plates are delivered in a normalized and tempered state, ensuring reliable performance even under prolonged thermal stress.
