Stainless Steel ER 316LSi Welding Wire features about 18% chromium, 12% nickel, 2–3% molybdenum, and an increased silicon content (around 0.65–1.0%) to enhance weld fluidity. Its low carbon content reduces the risk of intergranular carbide precipitation, boosting corrosion resistance. The austenitic weld deposit provides excellent mechanical strength, with a typical tensile strength of around 570 MPa, along with good elongation and crack resistance. Designed for use with inert gas shielding, ER 316LSi produces clean, smooth welds with minimal spatter, making it ideal for precision welding in sanitary and corrosive environments.
