AWS Class ER385 MIG and TIG filler welding wire and rods are used to fill stainless steels (high alloy, in particular, Type 904L). They are usually made of 0.02% carbon, 19-21% chromium, 24-26% nickel, 4-5% molybdenum, 1-2% copper and low levels of silicon and manganese, which give excellent pitting, crevice and overall corrosion resistance. ER385 is mechanically characterized by tensile that is 550-750 Mpa, yield that is approximately 350-480 Mpa and elongation that is 30-40%. Such properties guarantee strong, ductile, and corrosive resistant welds that can be used in the complicated chemical, marine, and pharmaceutical industries.

The AWS Class ER385 MIG and TIG Filler is a nickel-based alloy filler metal that includes chromium and molybdenum, crafted for superior corrosion resistance and high-temperature strength. Its well-balanced chemical makeup guarantees excellent toughness in the weld metal, good ductility, and resistance to hot cracking. This filler produces welds that boast stable mechanical properties, impressive tensile strength, and reliable performance even under thermal and mechanical stress. It features smooth arc characteristics in both MIG and TIG welding, leading to clean, dense weld deposits with consistent metallurgical integrity.
You’ll often find AWS Class ER385 MIG and TIG Filler being used for welding nickel-based alloys and for joining dissimilar metals that face corrosive and high-temperature conditions. Common applications include petrochemical equipment, chemical processing vessels, heat exchangers, power generation components, and offshore structures. It’s also a great choice for maintenance and repair welding, where resistance to corrosion, oxidation, and thermal cycling is crucial. This filler is widely utilized in industries like oil and gas, chemical processing, energy, and heavy manufacturing, all of which demand durable, high-integrity welds.
