AWS welding wire Hastelloy c-276 ERNiCrMo-4
INTRODUCTION
WISDOM 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.
