Stainless Steel Flux Core Wire

Material

Stainless steel flux core wire is a tubular consumable filled with a flux compound that shields the weld pool from air. It works well on austenitic, dissimilar, and stabilised stainless steel grades using the FCAW process.

SS flux cored wire deposits weld metal with strong corrosion resistance, low spatter, and fast deposition rates. These wires resist oxidation, pitting, and intergranular attack.

Engineers choose stainless steel FCAW wire for its high deposition rate on thick sections and all-position capability on pipe and plate joints.

Common applications include pressure vessels, process piping, heat exchangers, and storage tanks. Petrochemical, food processing, and power generation industries rely on stainless steel flux cored welding wire daily.

We at Nicorex Alloys stock and supply these wire grades from our Mumbai warehouse. As one of the leading stainless steel flux core wire suppliers and stockists, we serve fabricators and EPC contractors across India. We source these products from recognised producers.
