Lecong Stainless Manufacturer and Suppliers in Da Nang, Vietnam, offers AWS Class ER317L MIG and TIG filler wire and rod for stainless steel welding applications. This low-carbon filler metal is designed for molybdenum-bearing stainless steels, providing excellent resistance to pitting, crevice corrosion, and chloride attack. Its low carbon content reduces carbide precipitation, which helps maintain weld integrity in corrosive settings. With stable arc performance, great bead appearance, and smooth feeding, ER317L ensures consistent and reliable results. Lecong Stainless supplies this filler wire and rod to industries globally, ensuring high-quality welds in demanding chemical, marine, and industrial projects.
ER317L includes about 19% chromium, 13% nickel, and 3–4% molybdenum, with ≤0.03% carbon. This makeup provides strong corrosion resistance in chloride-rich and acidic environments. Mechanical properties feature a tensile strength of 80,000–85,000 psi, yield strength of about 55,000–60,000 psi, and elongation of 30–35%. The weld deposit shows toughness, ductility, and resistance to localized corrosion. With its low carbon design, ER317L reduces the risk of intergranular corrosion while ensuring reliable performance under both MIG and TIG welding processes, delivering durable joints for critical stainless steel applications.
