ED Stainless proudly provides high-performance Alloy 309LMo SAW wire and specialized flux for challenging welding tasks that require better corrosion and heat resistance. This alloy is a modified stainless filler metal with added Molybdenum to improve resistance to pitting and crevice corrosion. Ideal for submerged arc welding, the combination of 309LMo wire and our flux ensures smooth, high-quality welds with low spatter and high strength. ED Stainless supports the chemical, pharmaceutical, and offshore industries with weld materials designed for tough service conditions like chlorides, high humidity, and high operating temperatures.
Alloy 309LMo contains 23–25% Chromium, 12–14% Nickel, 2–3% Molybdenum, and low Carbon (≤0.03%). It provides a tensile strength of 550–580 MPa and strong resistance to localized corrosion. The additional Mo improves performance in acidic and chloride-rich environments. When combined with SAW flux, it produces a tough, ductile weld metal with great bead shape and penetration. This filler metal is suitable for dissimilar welding, cladding, and corrosion-resistant overlays, providing both mechanical integrity and corrosion protection in demanding operating conditions.
