Stainless Steel MIG & TIG Welding Consumables

MaterialStainless 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.

Complete Range of Stainless Steel MIG & TIG Welding Products

The majority of the welding requirements for stainless steel in industrial fabrication are met by the following grades.
Product Grade Best Metals They Can Weld Reason
AWS A5.9 ER308L/308H SAW & Flux
AWS A5.9 ER308L/308H SAW & Flux
304, 304L, 304H stainless steel Matches the 18Cr-8Ni chemistry of 304-type steels for strong, corrosion-resistant joints
Alloy 309LMo AWS A5.17 SAW & AWS A5.9 Flux
Alloy 309LMo AWS A5.17 SAW & AWS A5.9 Flux
Dissimilar joints: carbon steel to stainless steel Higher Cr and Ni content bridges the chemistry gap; added Mo improves pitting resistance
AWS A5.17 ER316L/316H SAW & Flux
AWS A5.17 ER316L/316H SAW & Flux
316, 316L, 316H stainless steel Contains 2-3% Mo for better resistance to chloride pitting and crevice corrosion

Quick Selection Matrix

Utilise this table to determine the appropriate filler metal for your undertaking in accordance with the base metal.
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
