Product Description
ASTM A240 321 321H Titanium Stabilized Hot Rolled Stainless Steel Plate No.1 Finish High Temperature Service
Product Introduction
ASTM A240 321 and 321H hot rolled stainless steel plates are titanium-stabilized austenitic grades designed for service in the carbide precipitation temperature range of 425-815°C (800-1500°F). The titanium addition (5*C minimum) preferentially combines with carbon, preventing chromium carbide formation at grain boundaries and eliminating intergranular corrosion susceptibility after welding or prolonged thermal exposure.
321H (UNS S32109), with higher carbon content (0.04-0.10%), provides enhanced elevated temperature strength and creep resistance for applications above 540°C. Available in No.1 finish, these plates are ideal for high-temperature pressure vessels, expansion joints, and refinery equipment where post-weld heat treatment is impractical.
