Harshita Stainless provides high-quality AWS Class ER317L MIG and TIG Filler Welding Wire and Rod, designed for superior corrosion protection and durability in harsh environments. Produced in both Dubai and India, ER317L is a low-carbon austenitic stainless steel filler metal that contains molybdenum. It is commonly used in pulp and paper, chemical, and marine industries where strong resistance to pitting and crevice corrosion is essential.
ER317L is made up of 18–20% chromium, 13–15% nickel, 3–4% molybdenum, and ≤0.03% carbon. The higher molybdenum content provides better resistance to pitting and crevice corrosion in environments with high chloride levels. It has a tensile strength of ≥75 ksi, yield strength of ≥55 ksi, and elongation of ≥30%. ER317L maintains the strength and toughness of welds even in aggressive conditions and during thermal cycling. This filler wire offers smooth control of the arc and excellent wetting during both MIG and TIG processes. Its low carbon content minimizes the risk of intergranular corrosion after welding, even in critical service conditions.
