- Stainless Steel MIG & TIG Welding Consumables
Stainless steel MIG & TIG welding requires filler metals that match the base metal’s chemistry. The wire and flux must resist corrosion, hold strength at service temperature, and produce clean welds with low spatter.Stainless fillers resist acids. They control the puddle and ensure fusion with austenitic grades. Use L grades to stop carbide formation. Choose H grades for creep strength. These properties are essential for high-temperature and corrosive industrial environments.
This product is preferred when the weld joint must perform the same as the parent metal. A correct filler metal keeps the corrosion barrier intact across the entire weld zone. This matters in acidic, chloride-rich, or high-temperature environments.
Diverse industries utilise these filler metals for everything from food processing to pharmaceutical piping. They power heat exchangers and pressure vessels in chemical plants, power stations, paper mills, and rugged offshore platforms.
Nicorex Alloys maintains an exhaustive stainless MIG and TIG inventory at its Mumbai warehouse. We actively support Indian fabricators, contractors, and project teams by providing the technical guidance and available stock required to complete complex welding projects on time.

316, 316L, 316H stainless steel | Contains 2-3% Mo for better resistance to chloride pitting and crevice corrosion |
Quick Selection Matrix
| Base Metal Being Welded | Recommended Product | AWS Class | Why This Choice |
|---|---|---|---|
| AISI 304L stainless steel | ER308L SAW & Flux | ER308L | Low carbon prevents carbide buildup at grain boundaries |
| AISI 304H stainless steel | ER308H SAW & Flux | ER308H | Higher carbon adds creep strength for elevated temperature service |
| AISI 316L stainless steel | ER316L SAW & Flux | ER316L | Mo content matches the base metal for chloride resistance |
| AISI 316H stainless steel | ER316H SAW & Flux | ER316H | Higher carbon version suited for elevated temperature service |
| Carbon steel to 304 stainless | Alloy 309LMo SAW & Flux | ER309LMo | Over-alloyed filler handles dilution from the carbon steel side |
| Carbon steel to 316 stainless | Alloy 309LMo SAW & Flux | ER309LMo | Mo addition gives pitting resistance in the mixed weld zone |
