What is AWS Class E312-16 Coated Electrodes?

The composition of Ultimet Coated Electrodes primarily includes cobalt, chromium, molybdenum, and nickel, creating a corrosion- and wear-resistant alloy with a fully austenitic microstructure. This unique blend provides remarkable resistance to galling, metal-to-metal wear, high-temperature oxidation, and a wide variety of corrosive chemicals. The electrodes boast impressive mechanical properties, featuring tensile strength exceeding 700 MPa, high ductility, and excellent impact toughness. They produce smooth, defect-free welds with minimal dilution and cracking. The alloy’s superior thermal stability ensures long-lasting protection in both low- and high-temperature service conditions.
