ASME SA 387 Grade 12 Class 1/2 Sheets and Plates are specially designed high-temperature, chromium-molybdenum alloy steels, perfect for pressure vessels and equipment that face intense heat. Shalan Steel, a trusted manufacturer and supplier located in Kuala Lumpur, Malaysia, provides top-notch SA 387 Gr 12 Cl 1 and Cl 2 plates throughout Malaysia and Southeast Asia, catering to critical needs in power generation, refining, and petrochemical sectors.
SA 387 Grade 12 features around 1% chromium and 0.5% molybdenum, which boosts its resistance to heat, oxidation, and hydrogen attack. Class 1 plates deliver a tensile strength ranging from 415 to 585 MPa, while Class 2 offers an even higher tensile strength between 515 and 690 MPa. Both classes maintain a minimum yield strength of 275 MPa and are usually supplied in a normalized and tempered state to guarantee consistent mechanical performance.
