What is AWS Class E312-16 Coated Electrodes?

AWS Class E312-16 coated electrodes are formulated with a high alloy composition containing approximately 29% Chromium and 9% Nickel, providing excellent resistance to cracking, oxidation, and corrosion. Their weld metal exhibits a fully austenitic structure with some ferrite, ensuring durability in demanding environments. Typical mechanical properties include a tensile strength of around 95,000 psi (655 MPa), yield strength of about 65,000 psi (450 MPa), and elongation of 25–35%. These electrodes deliver strong, tough welds, making them ideal for joining dissimilar steels and high-strength applications.
