The registered trademark name, Hastelloy, is applied as the prefix name to more than twenty different highly corrosion resistant metal alloys produced by Haynes International, Inc. These superalloys, or high performance alloys, developed by Haynes International, are nickel-based steel alloys that exhibit traits that include high resistance to uniform attack, localized corrosion/oxidation resistance, stress corrosion cracking resistance and ease of welding and fabrication.


Hastelloy applications

Like Inconel, Hastelloy can withstand high temperatures. The temperature this alloy can withstand can reach up to 1100 degrees Celsius. This property ensures that Hastelloy is suitable for parts of tools and machines that must withstand very high temperatures. Examples include aircraft engines and gas turbines.
