E7018

The world's most popular solid MIG/TIG welding wire for carbon steel. High manganese (1.40-1.85%) and silicon (0.80-1.15%) content provides superior deoxidizing power — welds cleanly even on slightly rusty or oily steel. Copper-coated for smooth wire feeding. Produces X-ray quality porosity-free welds with excellent bead appearance. Used with CO2 or Ar/CO2 shielding gas. Minimum 480 MPa tensile strength. Used for general fabrication, structural steel, shipbuilding, pressure vessels, automotive, and construction. The go-to wire for every MIG welder.

Low-carbon austenitic stainless steel welding wire — the standard filler for joining 304 and 304L stainless steels. The L (low carbon ≤0.03%) prevents sensitization and intergranular corrosion in the heat-affected zone. Used for TIG (GTAW) and MIG (GMAW) with pure argon or Ar/CO2 shielding. Produces fully austenitic-ferritic weld metal with 5-15 FN (Ferrite Number) for crack resistance. Used for food processing equipment, chemical tanks, pharmaceutical vessels, and architectural stainless fabrication.

Low-carbon molybdenum-bearing austenitic stainless steel welding wire — the standard filler for joining 316 and 316L stainless steels. 2-3% Mo provides superior pitting and crevice corrosion resistance versus ER308L, especially in chloride environments. Low carbon (≤0.03%) prevents sensitization. Used for TIG and MIG welding of chemical processing equipment, marine hardware, pharmaceutical vessels, pulp & paper digesters, and offshore piping. Also used for dissimilar joints between 304 and 316 grades.
