Low-manganese solid wire for submerged arc welding (SAW) — the highest deposition rate welding process (up to 20 kg/h). Used with agglomerated or fused flux (F7A2-EM12K classification). Tensile strength 70 ksi (485 MPa). Clean weld deposits with excellent mechanical properties. THE process for long straight welds: pipe longitudinal seams, vessel shell courses, shipbuilding panel lines, structural beams and heavy plate fabrication. Multi-wire SAW (tandem/twin) for maximum productivity.

Duplex stainless steel solid wire for GMAW/GTAW welding of duplex grades 2205 (1.4462) and similar. Cr 22%, Ni 8–10%, Mo 3%, N 0.10–0.20%. Overalloyed in Ni compared to the base metal to ensure correct 50/50 ferrite-austenite balance in the weld deposit. Critical for offshore, chemical, pulp & paper and desalination plant applications. Achieves PREN >30 and excellent resistance to chloride stress corrosion cracking and pitting.

Super duplex stainless steel solid wire for GMAW/GTAW welding of super duplex grades 2507 (1.4410) and similar high-PRE alloys. Cr 25%, Ni 9.5%, Mo 4%, N 0.22–0.30%. Overalloyed in Ni to ensure correct ferrite-austenite balance in weld deposit. PREN >40 in the weld metal. Used for offshore platforms, subsea manifolds, seawater systems, chemical tankers and desalination plants. Critical that interpass temperature stays below 150°C.

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.

Austenitic stainless steel solid wire for GMAW/GTAW welding of dissimilar joints (stainless to carbon steel) and for cladding carbon steel with stainless overlay. Higher Cr (23–25%) and Ni (12–14%) content ensures crack-free austenitic weld deposits when diluted with carbon steel base metal. Low carbon (max 0.03%) prevents sensitization. Also used as first layer when welding 304/316 to carbon steel, and for repair welding of cast stainless steels.

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.

Carbon steel solid wire for GMAW/GTAW with lower deoxidizer content than ER70S-6. Produces cleaner welds with less silicon island formation — preferred for single-pass welds on clean, mill-scale-free steel. Tensile strength 70 ksi (485 MPa). Less forgiving than ER70S-6 on dirty or rusty steel. Standard wire for precision fabrication, sheet metal, automotive and applications where post-weld cleaning or painting is critical.

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.

Chromium-molybdenum solid wire (1.25% Cr, 0.50% Mo) for GMAW/GTAW welding of creep-resistant CrMo steels like 13CrMo4-5 (T11/P11) and similar grades. Tensile strength 80 ksi (550 MPa). Designed for power plant piping, boiler components, refinery equipment and pressure vessels operating at 450–550°C. PWHT (post-weld heat treatment) required at 690–720°C. Matching filler for ASTM A335 P11 pipe.

Nickel-chromium solid wire matching Inconel 600 (N06600). Ni-balance with ~20% Cr and ~3% Mn + Nb. The standard filler for GTAW/GMAW welding of Inconel 600/601, dissimilar welds between nickel alloys and stainless/carbon steels, and for surfacing austenitic stainless steels with nickel alloy overlay. Excellent resistance to hot cracking. Used in power generation (nuclear steam generators), chemical processing, furnace components and heat-resisting applications. Also known as Inconel Filler Metal 82.

Nickel-chromium-molybdenum solid wire matching Inconel 625 (N06625). 22% Cr, 9% Mo, 3.5% Nb. The workhorse wire for GMAW/GTAW welding of nickel alloys, dissimilar joints (Ni alloy to stainless/carbon steel), corrosion-resistant overlay cladding and repair welding. Outstanding resistance to pitting in chloride environments. Also used for welding 9% Ni cryogenic steels (ASTM A553). Shielding: pure Ar or Ar/He for GTAW, Ar/He/CO2 mix for pulsed GMAW.

Nickel-iron-chromium solid wire matching Inconel 718 (N07718). Ni 50–55%, Cr 17–21%, Nb+Ta 4.75–5.50%, Mo 2.8–3.3%. Age-hardenable weld deposit reaching UTS >1000 MPa after PWHT. Used for GTAW/GMAW welding of Inconel 718, dissimilar joints in aerospace (turbine discs, casings) and oil & gas (subsea, HPHT). Post-weld aging at 720°C/8h + 620°C/8h required for full strength. Also designated as Inconel Filler Metal 718.
