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.

Mo-bearing stainless steel SMAW electrode for dissimilar joints where the base metals include Mo-bearing grades (316L, 317L). 23% Cr, 13% Ni, 2.5% Mo. Low carbon (≤0.03%) for intergranular corrosion resistance. The correct choice when cladding with 316L-type overlay on carbon steel — standard E309L lacks Mo and underdilutes. AC or DCEP. Used for first-layer cladding in chemical/petrochemical vessels, transition joints between 316L piping and carbon steel.

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.

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.

High-cellulose potassium coated SMAW electrode — the AC-capable version of E6010. Deep penetrating, forceful arc with fast-freeze slag. Runs on both AC and DCEP, making it usable with smaller transformer-type welding machines. Tensile strength 60 ksi (414 MPa). Same cellulose coating system as E6010 — do NOT rebake. Used for pipeline root passes (when DCEP machine not available), field erection, maintenance welding and dirty/rusty steel.

Rutile-coated all-position SMAW electrode for AC and DC±. Smooth, stable arc with low spatter and easy slag removal — the most beginner-friendly stick electrode. Tensile strength 60 ksi (414 MPa). Medium penetration. Excellent for sheet metal, thin-wall tubing, general light fabrication and maintenance welding. Not suitable for critical structural or pressure vessel applications. Rebake at 70–100°C for 1h if damp.

The world's most widely used low-hydrogen SMAW (stick) welding electrode. Iron powder + calcium fluoride coating produces smooth, easy-to-control arc with minimal spatter and easy slag removal. Low hydrogen designation prevents hydrogen-induced cracking in structural joints. All-position welding (1 = flat, horizontal, vertical, overhead). AC or DCEP. Minimum 480 MPa tensile strength. Must be stored in heated ovens (250-300°F) to prevent moisture pickup. Used for structural steel, bridges, buildings, pressure vessels, and all code-compliant fabrication per AWS D1.1.

Low-hydrogen basic coated SMAW electrode with enhanced toughness (-45°C) and moisture-resistant coating (H4R designation = max 4ml H₂/100g, moisture-resistant). The premium structural steel electrode for critical applications: bridges, high-rise buildings, offshore structures, pressure vessels (ASME Section IX) and seismic-resistant frames. 70 ksi (485 MPa) tensile strength. AC or DCEP. The "-1" suffix indicates 27J impact at -45°C. H4R coating resists moisture pickup for 9+ hours after removal from hermetically sealed packaging.

Low-hydrogen basic coated SMAW electrode with 2.5% Ni for low-temperature service. Tensile strength 80 ksi (550 MPa). Impact toughness 27J at -60°C. Used for welding fine-grain structural steels, pressure vessels and storage tanks in cryogenic and sub-zero applications (LNG, ammonia, cold storage). Rebake 300–350°C for 1-2h before use. AC or DCEP. Meets requirements of ASME Section IX for low-temp service.

Nickel-chromium-molybdenum coated SMAW electrode matching Inconel 625 composition. 22% Cr, 9% Mo, 3.5% Nb. Used for welding Inconel 625, Incoloy 825, dissimilar joints between nickel alloys and stainless/carbon steels, and overlay cladding for corrosion protection. Outstanding resistance to pitting, crevice corrosion and stress corrosion cracking. DCEP. Also used for repair welding of 9% Ni cryogenic steels (LNG tanks). Rebake 250–300°C for 1h.
