ASME SA 387 Gr. 22 Cl. 1 & Cl. 2 Plates

Product Overview

ASME SA 387 Grade 22 Class 1 and Class 2 Plates are chromium-molybdenum alloy steel plates designed for elevated temperature and pressure service, especially in boilers, heat exchangers, pressure vessels, oil refineries, and chemical plants. With a Cr-Mo composition (2.25% Cr, 1% Mo), these plates exhibit excellent creep resistance, oxidation resistance, and thermal stability.

Class 2 provides higher tensile strength than Class 1 while both offer excellent weldability and durability under harsh working conditions.

• Superior mechanical strength at high temperatures

• Excellent creep and rupture resistance

• Good resistance to oxidation, corrosion, and hydrogen attack

• Available in normalized and tempered condition

• Compatible with welding and forming processes

• Ultrasonic Testing (UT) – As per EN 10160 / ASTM A578

• Charpy Impact Testing – Optional or as per order

• Tensile and Elongation Testing
