EM12K (SAW Wire)
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.

ER308L
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.
E6010
High-cellulose sodium coated SMAW electrode for pipeline welding. Produces a deep penetrating, high-force spray arc with fast-freeze characteristics and minimal slag. The standard electrode for root pass welding in pipeline construction (API 5L X42/X46). DCEP only. Tensile strength 60 ksi (414 MPa), yield 48 ksi (331 MPa). Impact toughness 27J at -30°C. Do NOT rebake — cellulose coating requires 3–7% moisture for proper operation. Also used for field erection, tank repair and welding on dirty/rusty steel.
E309L-16
Rutile-coated stainless steel SMAW electrode for welding dissimilar joints (stainless to carbon steel), stainless steel cladding and overlay welding. 23% Cr, 13% Ni ensures austenitic weld deposit even with dilution from carbon steel base. Low carbon (≤0.03%) for intergranular corrosion resistance. AC or DCEP. Smooth arc, easy slag removal. Used for first layer cladding on pressure vessels, repair of stainless castings and transition joints in process piping.
