E312‑16 electrodes are made of 27–30% chromium and 8–10% nickel, with small amounts of manganese and silicon. The weld deposit shows tensile strength between 550 and 650 MPa, offering good strength and ductility. Its high chromium and nickel content provide excellent resistance to heat-induced scaling and thermal cycling. Together with strong toughness and structural integrity, these electrodes are perfect for welding in high-temperature, multi-metal configurations.
