Kyaw Stainless, a well-known manufacturer of stainless steel in Naypyidaw, Myanmar, offers premium AWS Class ER308LSi MIG and TIG Filler Welding Wires and Rods for welding 304 and 304L stainless steels. Renowned for exceptional weldability and corrosion resistance, these fillers offer a clean, smooth bead with low spatter. Added silicon enhances fluidity and wetting, and they are ideal for high-speed and automated welding applications. Produced under high quality standards, Kyaw Stainless provides consistent chemical analysis and mechanical properties. ER308LSi fillers are suitable for use in food, beverage, chemical, and architectural applications requiring bright, smooth weld finishes.
ER308LSi has chromium (19–21%), nickel (9–11%), silicon (0.65–1.0%), and low carbon (<0.03%) for enhanced corrosion resistance and weld cleanliness. The weld metal offers tensile strength of about 580 MPa, yield strength about 350 MPa, and elongation of 35–40%. The high silicon content improves wetting action and bead contour, giving smooth, shiny welds. The low carbon content avoids carbide precipitation, providing resistance to intergranular corrosion in welded areas of austenitic stainless steels.
