Here’s a quick look at the **[ER310 MIG/TIG Filler Wire and Rod]()** (AWS Class ER310), which is perfect for use in manufacturing, supply catalogs, or technical documents:
ER310 solid welding wire and rod falls under the American Welding Society specification A5.9 / American Society of Mechanical Engineers SFA 5.9. It’s designed for MIG (GMAW) and TIG (GTAW) welding of fully austenitic stainless steels that have a high chromium and nickel content—think alloys with around 25% chromium and 20% nickel. ([Hindustan Inox][1]) This filler metal is crafted for weld deposits that need to handle high temperatures, resist oxidation and scaling, and join similar or different materials in tough fabrication scenarios.

Excellent corrosion resistance and high-temperature strength, ideal for welding stainless steels and dissimilar metals in industries like petrochemical and power generation.
Superior oxidation resistance and durability for precision welding of stainless steels and dissimilar alloys, suitable for high-temperature applications in chemical processing and aerospace.
Excellent resistance to oxidation and corrosion, perfect for high-temperature welding of stainless steels and dissimilar metals, used in demanding industrial environments.
AWS Class ER310 MIG and TIG filler wire and rod are widely applied in industries like power generation, petrochemical, furnace production, and heat treatment. They are specifically suited for welding high-temperature equipment, including heat exchangers, furnace parts, kilns, and burners, where oxidation resistance is critical. They are also applied for overlay and joining dissimilar metals in harsh environments. Their resistance to sustained exposure at high temperatures makes them invaluable in welding applications with demanding thermal and mechanical properties.
ER310 filler wire and rod is particularly well-suited for welding fully austenitic stainless steels (25% Cr – 20% Ni) in situations that demand high-temperature performance (up to about 1,100 °C) and outstanding oxidation/scale resistance. ([Raajratna Electrodes][5])
