Lecong Stainless Manufacturer and Suppliers in Da Nang, Vietnam, offers high-quality stainless steel consumables like 309LMo MIG and TIG filler wire and rod. This product is designed for welding stainless steels and mixed metals where added corrosion resistance is important. Molybdenum enhances protection against pitting and crevice corrosion, especially in chloride-rich environments. With stable arc performance, smooth feeding, and a superior weld bead, 309LMo creates strong and long-lasting joints. Lecong Stainless supplies this filler wire and rod to industries in Vietnam and around the world, meeting international standards for challenging welding tasks.
Alloy 309LMo MIG and TIG filler welding wires and rods are specifically designed for welding high-alloy materials. Providing exceptional corrosion resistance and strength at high temperatures. The addition of molybdenum (Mo) enhances the pitting and crevice corrosion resistance of the alloy, making it suitable for harsh environments. Its specificity contains 23% chromium, 13% nickel and 2-3% molybdenum, and low carbon content to prevent carbide precipitation and intergranular corrosion this alloy is ideal for disproportionate steel, over leveling, chemical processing, petrochemicals and power generation industries to include and applications, ensuring durable, high-quality welds.
