Hastelloy C22

Hastelloy C22

HASTELLOY Alloy C-22 is a nickel-chromium-molybdenum alloy with enhanced resistance to pitting, crevice corrosion, and stress corrosion cracking. It resists the formation of grain boundary precipitates in the weld-heat affected zone making it suitable for use in the as-welded condition. C-22 has outstanding resistance to both reducing and oxidizing media and because of its resistibility.

Application Industries

These materials are not a single material but the name for a family of corrosion resistant steels. Like many scientific breakthroughs, the origins of stainless steel lies in a lucky accident. From the smallest part of the zipper to the largest building skyscraper.
Metal fabrication is widely used across various industrial sectors such as mining, construction, manufacturing, shipbuilding, automotive, aerospace, and energy.
