The electrode is suitable for welding similar grades of steel. It has a good fabricability, and high resistance to oxidation in temperatures of up to 8000 C. the alloy is highly resistant to pitting, stress cracking corrosion and crevice corrosion. The electrode can withstand oxidizing agents like nitric acid and chloride ions even at high temperatures. The rods require heat treatment to improve the hardness. The alloy contains the high composition of nickel, chromium, and molybdenum that enhance its quality. The filler metal does not allow the formation of carbide precipitates around the welding zone.
