Stainless steel alloy 321, UNS S32100, type 321 datasheet

Stainless steel alloy 321 (UNS S32100) is a titanium stabilized austenitic stainless steel with excellent corrosion resistance and high temperature performance. Its titanium element effectively prevents the precipitation of chromium carbide, enhances its resistance to intergranular corrosion, and is suitable for oxidative environments below 800 ℃. It is widely used in fields such as aviation, chemical engineering, and heat exchangers.

Stainless steel alloy 321 material has good weldability and formability, excellent mechanical properties, a tensile strength of 520MPa, a yield strength of 205MPa, and an elongation of 40%. Its comprehensive performance makes it an ideal choice for high temperature and corrosive environments, ensuring the long-term stable operation of the equipment.
