ASME SA 387 Grade 22 Class 1/2 Sheets and Plates are top-notch chromium-molybdenum alloy steels crafted for pressure vessels and components that need to perform in high-temperature settings. Shalan Steel, a trusted manufacturer and supplier located in Kuala Lumpur, Malaysia, provides high-quality SA 387 Gr 22 Cl 1 and Cl 2 plates to clients throughout Malaysia and Southeast Asia, specifically for critical high-temperature applications.
SA 387 Grade 22 features 2.25% chromium and 1% molybdenum, which gives it remarkable resistance to heat, oxidation, and hydrogen attack. Class 1 boasts a tensile strength ranging from 415 to 585 MPa, while Class 2 steps it up with a higher tensile strength of 515 to 690 MPa. Both classes have a minimum yield strength of 275 MPa and are usually normalized and tempered to boost their creep strength and durability when faced with thermal stress.
