Vinit Stainless stands out as a top-notch manufacturer and supplier of AWS Class ER312 MIG and TIG Filler Welding Wire and Rod, proudly rooted in Chennai, India. Our ER312 filler metal is expertly crafted for welding dissimilar steels and those tricky alloys, offering remarkable crack resistance and robust weld deposits. It’s a go-to choice for joining stainless steels with carbon or low-alloy steels, as well as for repair welding when the base metal’s composition is a bit of a mystery. Produced under strict AWS standards, our ER312 wires and rods guarantee stable arc performance, minimal spatter, and clean, reliable welds, making them perfect for demanding fabrication and maintenance tasks across a variety of industries.
AWS Class ER312 MIG and TIG filler welding wire and rod are intended to weld disproportionate steel and high strength steel. They provide exceptional strength and toughness as well as excellent crack and corrosion resistance. The specific composition of ER312 contains 28-30% chromium and 20-22% nickel. Which improve corrosion resistance and improves weld properties. The alloys high chromium-nickel content allows it to handle high-stress applications and maintain durability in critical conditions. ER312 is commonly used in applications such as construction, shipbuilding and heavy machinery, where a strong and flexible weld is required in addition to imperfect surfaces or complex components.
