- Chrome Moly MIG & TIG

Chrome moly MIG & TIG filler wires are solid wire consumables for welding chromium-molybdenum alloy steels. These steels serve in high-temperature, high-pressure piping and pressure vessels. The filler wire must match the base metal’s chromium and molybdenum content to maintain creep strength and oxidation resistance.
These wires have high creep resistance, stable microstructure at elevated temperatures, and strong resistance to hydrogen-induced cracking. Each grade contains specific chromium and molybdenum levels that align with the base steel it joins.
Engineers choose chrome moly MIG and TIG wires because they create welds that can handle long-term heat and pressure. By matching the alloy chemistry of the wire to the base metal, the weld area stays uniform and avoids weak spots.
These wires are commonly used in Oil refinery piping, Power plant boiler tubes, Heat exchangers, and Petrochemical reactors. They are a standard choice in power generation, oil and gas, and chemical processing plants whenever strong, reliable high-temperature joints are required.
Nicorex Alloys supplies a full range of chrome moly MIG & TIG filler wires from our Mumbai facility. We stock all major grades for fast delivery across India. As a supplier and stockist, we serve refineries, power plants, and fabrication shops with tested material.
