Hastelloy is a nickel-based corrosion-resistant alloy, which is mainly divided into two categories: nickel-chromium alloy and nickel-chromium-molybdenum alloy. Hastelloy has good corrosion resistance and thermal stability, and is mostly used in aviation, chemical fields, etc.
ERNiCrMo-4 is used for gas-tungsten-arc and gas-metal-arc welding of Inconel alloy C-276 and other nickel-chromium-molybdenum alloys. Due to high molybdenum content, this alloy offers excellent resistance to stress corrosion cracking and pitting and crevice corrosion.
