Hastelloy C22 Bars - UNS N06022

Hastelloy C-22 （UNS N06022） is a versatile nickel-chromium-molybdenum-tungsten alloy renowned for its exceptional resistance to a wide range of corrosive environments, including both oxidizing and reducing conditions. This alloy offers superb resistance to pitting, crevice corrosion, and stress corrosion cracking in harsh chemical environments containing chlorides, sulfuric acid, phosphoric acid, and other aggressive chemicals.

 

Hastelloy C22 Bars are corrosion-resistant nickel, chromium, molybdenum, tungsten alloy bars distinguished by their exceptional resistance to various corrosive media, pitting, crevice corrosion and stress corrosion cracking among them, making them suitable for use in environments exposed to such agents such as chemical processing facilities where these agents may be found in abundance.

Its composition includes nickel, chromium, molybdenum, tungsten, and trace amounts of other elements. Hastelloy C-22 is commonly used in various applications across chemical processing, pollution control, pulp and paper, and pharmaceutical industries. Its properties make it well-suited for use in reactors, heat exchangers, scrubbers, and other equipment where corrosion resistance and reliability are paramount.

From creating reactors, vessels, heat exchangers and piping systems for handling aggressive chemicals to producing pumps, valves and fittings used by chemical processing plants, its versatility and high temperature resistance make these bars invaluable in critical situations that demand resistance against corrosion and high temperatures.

Hastelloy C22 Bars exhibit superior machinability features. While conventional tools and methods may suffice, due to their strength and work hardening rate they require specific techniques or tooling in order for optimal machining results. With proper equipment and techniques these bars can efficiently meet various dimensional requirements efficiently.

 

Hastelloy C22 Bars stand out as being particularly weldable materials. You can weld these bars using standard welding techniques such as gas tungsten arc welding (GTAW), gas metal arc welding (GMAW) and shielded metal arc welding (SMAW), making for convenient fabrication of complex structures or components without restricting design flexibility or construction techniques.
