Is Hastelloy magnetic or not?
What is Hastelloy C276?
Hastelloy C276, also known as nickel alloy C276, is a solution annealed nickel-molybdenum-chromium alloy with the addition of tungsten.
Due to the high nickel content, C276 alloy is not susceptible to chloride-induced stress corrosion cracking. The high molybdenum and chromium contents enable the alloy to maintain good performance in oxidizing, non-oxidizing and mixed acid media, while also exhibiting excellent resistance to pitting and crevice corrosion. The addition of tungsten inhibits the formation of pitting.
Therefore, C276 is the most versatile corrosion-resistant material currently available and is well suited for use in a variety of harsh environments.
The following is an overview of the key properties and applications of Hastelloy C276.
