What is AWS Class E312-16 Coated Electrodes?

AWS E312-16 is a high-alloy austenitic stainless steel electrode that contains around 28–32% chromium and 8–10% nickel. This distinctive blend results in a robust, crack-resistant weld metal with a high ferrite content, making it very tolerant to dilution. The weld metal produced boasts exceptional tensile strength, good ductility, and remarkable resistance to impact and thermal shock. These electrodes ensure stable arc characteristics, a smooth bead appearance, and dependable mechanical performance even in tough welding conditions.
