Harshita Stainless, a leading manufacturer and supplier located in Delhi, India, specializes in high-quality AWS Class ER310 MIG and TIG Filler Welding Wire and Rod, perfect for welding heat-resistant stainless steels. The ER310 is crafted specifically for high-temperature and oxidation applications, making it ideal for joining Type 310 stainless steel and other high-alloy steels. Renowned for its superb arc stability, smooth bead finish, and minimal spatter, this filler metal guarantees strong, corrosion-resistant welds, even in extreme heat. Harshita Stainless is committed to delivering reliable performance and consistent quality, serving demanding sectors like furnace fabrication, power generation, petrochemicals, and metallurgy.
When it comes to composition and mechanical properties, AWS Class ER310 filler wire and rod typically consist of 25–28% Chromium and 20–22% Nickel, providing outstanding resistance to oxidation and scaling at temperatures reaching up to 1100°C. The low carbon content helps minimize the risk of carbide precipitation, ensuring corrosion resistance remains intact. Mechanical properties usually feature a tensile strength of around 580 MPa, yield strength of about 360 MPa, and an elongation of 30%. Designed for both GTAW (TIG) and GMAW (MIG) processes, ER310 delivers smooth arc performance, clean weld profiles, and impressive mechanical strength in high-temperature, thermally cycling environments.
