Introduction

This alloy exhibits excellent corrosion resistance to most corrosive media in both oxidation and reduction states. Excellent resistance to point corrosion, crevice corrosion, and stress corrosion cracking. Alloy is suitable for various chemical process industries containing oxidizing and reducing media. The higher content of molybdenum and chromium makes the alloy resistant to chloride ion erosion, and the tungsten element further improves its corrosion resistance. Hastelloy C-276 is one of the few materials that can withstand corrosion from moisture, hypochlorite, and chlorine dioxide solutions. This alloy exhibits significant corrosion resistance to high concentrations of chloride solutions, such as iron chloride and copper chloride.
