Weston Stainless, Midland, UK, is a top-tier supplier of premium stainless steel welding consumables across various industrial sectors. One of its high-end products is AWS Class ER308LSi MIG and TIG Filler Welding Wire and Rod for welding 304 and 304L stainless steels. This low-carbon austenitic stainless steel filler metal is stabilized with higher silicon content for added weld pool wetting and fluidity and lowered carbide precipitation. ER308LSi can be supplied as wire or rod and provides optimal corrosion resistance, high mechanical properties, and very good weldability for challenging welding applications.
AWS Class ER308LSi MIG and TIG Filler Welding Wire and Rod have 19-21% chromium, 9-11% nickel, and 0.65-1.00% silicon and a maximum 0.03% carbon to provide superior corrosion resistance and weld bead smoothness. These fillers have tensile strength of approximately 600 MPa, yield strength of about 300 MPa, and elongation of 35%. With a 7.9 g/cm³ density and a melting range of 1350-1400°C, ER308LSi offers greater thermal stability, resistance to oxidation, and better welding performance, especially in automated welding.
