Hastelloy C22, designated UNS N06022, is a nickel-based alloy enhanced with chromium, molybdenum, and tungsten. This specific chemistry provides excellent resistance against both oxidizing and reducing agents. Unlike many alloys that perform well in one type of chemical environment but fail in another, Hastelloy C22 offers a rare combination of broad-spectrum corrosion resistance.

Our Hastelloy C22 Tubes are produced according to international standards, including ASTM B622 for seamless tubes. These tubes are widely chosen because they provide structural integrity, dimensional precision, and resistance to localized corrosion, even in chloride-rich media where stainless steels often fail.

At DLX, our focus is not only on material quality but also on ensuring customers receive solutions that align perfectly with their applications.
