AWS Class E309LT0-1/T0-4 flux core wires are designed for welding stainless steel, particularly 309 and 309L grades. Composition typically includes 23–25% Chromium (Cr), 12–14% Nickel (Ni), and low Carbon (C ≤0.08%), with minor amounts of Manganese (Mn) and Silicon (Si), ensuring corrosion resistance and weldability. Mechanical properties deliver excellent strength and ductility, with tensile strength around 540–650 MPa, yield strength approximately 310–380 MPa, and elongation of 35–40%. These wires provide stable arc performance, minimal spatter, and superior impact toughness, making them ideal for joining dissimilar stainless steels and high-temperature applications.
