Hastelloy C4 solves the problem that standard stainless steel pipes and stainless steel pipe fittings often lack the durability needed in corrosive environments. Known for its stability, it also offers corrosion resistance.
What is Hastelloy C4 | UNS N06455
Hastelloy C4 is a nickel-chromium-molybdenum alloy that belongs to the Hastelloy alloy family,Hastelloy C Series. It is a solid solution alloy, meaning that it cannot be age-hardened. The very low carbon content, combined with its special composition, makes it very stable and resistant to sensitization.

Key Advantages of Hastelloy C4
Hastelloy C4 is resistant to a wide range of corrosive media, with both oxidizing and reducing environments, as well as stress corrosion cracking.
It is very stable at high temperatures and prevents sensitization. This means that its corrosion resistance remains after welding.
Hastelloy C4 is easy to weld and easy to form. This ensures that complex welding and fabrication processes can be simplified.
Hastelloy C4 excels in many industries, including chemical processing, pollution control and food processing.
