ER317L MIG & TIG Welding Wire

At Metals And Welding Specialities, the ER317L MIG & TIG Welding Wire welding wire stands out as a premium solution for fabricators and manufacturers who demand exceptional corrosion resistance, superior weldability, and consistent mechanical performance. Designed for critical applications where strength and resistance to aggressive environments are essential, this alloy delivers high-quality welds with reduced carbon content, minimizing carbide precipitation and ensuring long-term stability in service.

The ER317L wire corresponds to UNS S31703 and meets the requirements of ASTM A580 standards. This austenitic stainless steel filler metal is engineered for both MIG (GMAW) and TIG (GTAW) welding processes, offering excellent versatility across a range of industrial applications. Its molybdenum-rich composition, typically around 3–4%, enhances resistance to pitting and crevice corrosion, especially in chloride-bearing environments where conventional grades like ER316L might fall short.

Welders trust ER317L stainless steel wire for its smooth arc stability, clean bead appearance, and minimal spatter, resulting in efficient, high-quality fabrication. The low carbon level (≤0.03%) ensures superior intergranular corrosion resistance, making it suitable for use in chemical processing plants, marine systems, paper and pulp production, and desalination equipment. When used with an appropriate shielding gas, it maintains excellent weld pool control and consistent penetration, which are vital for precision joints and structural integrity.

The ER317L MIG & TIG wire from Metals And Welding Specialities is manufactured to strict quality control standards to ensure uniform wire diameter, precise chemical balance, and reliable feedability. Each spool undergoes rigorous inspection to guarantee defect-free performance and repeatable results in demanding environments. Whether used for overlaying, joining dissimilar metals, or fabricating stainless steel components, this filler metal provides consistent metallurgical integrity and corrosion protection across every weld seam.

Its compatibility with base metals such as ASTM 317L, 316L, and similar stainless steels allows seamless integration into existing welding operations. The ER317L TIG rod is equally efficient in manual and automated systems, delivering strong, durable welds even under fluctuating temperature and pressure conditions. The combination of nickel, chromium, and molybdenum ensures outstanding resistance to sulfuric acid, acetic acid, and other harsh chemical agents, making it ideal for industries that cannot afford material degradation or weld failure.

By choosing Metals And Welding Specialities’ ER317L MIG & TIG Welding Wire, users benefit from a product that merges technical excellence with operational dependability. Our commitment to quality ensures that every batch meets international standards and customer specifications, providing peace of mind and performance you can trust for every weld.
