Audited Supplier Hastelloy C-22 Nickel base corrosion resistant alloy Seamless tube N06022
Introduction
Hastelloy C-22 is one of the most widely used nickel-chromium-molybdenum-tungsten alloys. It has better resistance to uniform and local corrosion and is suitable for a variety of mixed industrial chemicals. HC-22 has better corrosion resistance than other Ni-Cr-Mo alloys, including C-276, C-4 and 625. C-22 alloys have excellent weldability.
