Nickel Alloy 22 Product Guide
Applications | Specifications | Mechanical and Chemical Data | Tolerances
Overview
Nickel Alloy 22 is an fully austenitic advanced corrosion-resistant alloy with superior corrosion resistance to both C276 and 625. It provides resistance to both oxidizing and reducing media. Due to these qualities, Alloy 22 is used in several agressive environments, such as oil and gas, waste water treatment, chemical processing, food processing, & polution control. Additionally, Alloy 22 is ductile enough to be cold worked and exhibits great weldability.
