Khaleed Stainless stands out as a top manufacturer and supplier of 309LMo MIG and TIG Filler Welding Wire and Rod in Riyadh, Saudi Arabia. We pride ourselves on delivering high-quality welding consumables that meet the demands of various industrial applications. This particular alloy is crafted for welding stainless steels, especially when dealing with dissimilar joints and overlays that require exceptional corrosion and oxidation resistance. The inclusion of molybdenum significantly boosts its ability to resist pitting, crevice corrosion, and harsh acidic environments. Our 309LMo MIG and TIG Filler Welding Wire and Rod ensure excellent arc stability, smooth weld deposits, and reliable performance in both MIG and TIG processes, making them perfect for critical applications.
The 309LMo MIG and TIG Filler Welding Wire and Rod are composed of chromium (23–25%), nickel (12–14%), and molybdenum (2–3%), all while maintaining low carbon levels to minimize carbide precipitation. This well-balanced composition provides outstanding corrosion resistance, particularly in environments rich in chloride and sulfur. The weld metal boasts a tensile strength of approximately 550–650 MPa, a yield strength of 300–350 MPa, and an elongation of around 30–35%. It guarantees high toughness, ductility, and creep resistance at elevated temperatures, all while ensuring excellent weldability and crack resistance.
