Alloy 309LMo SAW wire and flux are designed for high-temperature and corrosion-resistant applications. The composition typically includes 23–25% Chromium, 12–14% Nickel, and 1–2% Molybdenum, with low carbon content to minimize carbide precipitation. Mechanically, it offers excellent tensile strength, usually around 520–620 MPa, with good yield strength and elongation of 30–40%, ensuring ductility and toughness. This alloy exhibits superior resistance to oxidation, scaling, and pitting at elevated temperatures, making it ideal for welding austenitic stainless steels, dissimilar metal joints, and critical industrial components exposed to harsh environments.
