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.

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.
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.
E316L-16
Rutile-coated austenitic stainless steel SMAW electrode matching 316L (1.4404). 18.5% Cr, 12% Ni, 2.5% Mo, max 0.03% C. Smooth arc, fine ripple bead, easy slag removal. AC or DCEP. For welding 316, 316L and similar Mo-bearing austenitics in food/pharma/chemical processing. Resistant to intergranular corrosion after welding. Used for tanks, vessels, piping and equipment in contact with acids, chlorides and process media.
