Hastelloy Forgings are primarily composed of nickel, with significant additions of chromium and molybdenum to enhance corrosion resistance and high-temperature strength. Small amounts of iron, cobalt, and tungsten may also be included depending on the grade. This composition provides excellent tensile strength, yield strength, and toughness even under extreme pressure and heat. Hastelloy forgings exhibit outstanding resistance to oxidation, pitting, crevice corrosion, and stress corrosion cracking, ensuring stable mechanical performance in aggressive chemical environments.
