Product Description
Hastelloy C-22 Plate & Round Bar, Tube
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 offers superior resistance to both uniform and local corrosion, making it suitable for various mixed industrial chemicals. HC-22 provides better corrosion resistance than other Ni-Cr-Mo alloys, including C-276, C-4, and 625. C-22 alloys also feature excellent weldability.
