AWS Class ER316LSi filler wires have 17–19% chromium, 12–14% nickel, 2–3% molybdenum, 0.65–1.0% silicon, and <0.03% carbon to avoid the precipitation of carbides. The mechanical properties are tensile strength of approximately 580 MPa, yield strength of 400 MPa, and elongation of about 35%. The increased silicon content enhances arc stability, bead wetting, and fluidity, resulting in smooth, shiny surfaces on the welds. The weld metal possesses superior corrosion resistance in chloride and acid environments and thus is qualified for applications requiring higher mechanical and metallurgical performance.
