- All position welding of heat resistant 22-25% chromium and 12-13% nickel Stainless steels such as 309/309L to itself, to other austenitic Cr-Ni grades such as 304L, 308L, 310, 316L, 321 or 347 as well as martensitic grades 410, 420, 431, and ferritic Stainless grades such as 430, 442, and 446; all of these Stainless steel grades can be welded to each other or to mild and carbon steels.

- The low carbon content of this electrode (0.04% C) preserves the intergranular corrosion-resistant properties of the weld deposit and ensureSÜA higher ferrite content than Standard309-16; most 309L-16 weld depositSÜAre greater than 8 FN.
- Weld deposits exhibit high resistance to cracking and oxidation at temperatures up to 2000 ºF. Excellent for welding dissimilar steels or overlaying unalloyed structural steels found in furnace parts, kiln linings, heat treatment containers, forging and castings in chemical, petrochemical, power generation and pharmaceutical industries.
- These Electrodes are available in Sizes: 3/32" and 1/8" - Available Packages: 0.5 Lb, 2 Lb and 4.4 Lb - Select your option from the Size Menu - Check Picture #2 for an approximate number of electrodes per pound - 3/32" electrodes are 12" long and 1/8" electrodes are 14" long
Instructions: Use DC+ (reverse polarity), however, an AC machine with sufficient open circuit voltage may be used. Bevel thick sections to a 60º Vee. Clean the weld zone of all contaminants. Preheating 300 series Stainless steel is NOT required. The diameter of the electrode chosen should be equal to the thickness of the base metal. Use the lowest possible welding current or increase your welding speed in order to avoid overheating or distortion of the base metal. Overheating Stainless steel can degrade the composition and corrosion resistant properties. The arc length should be kept as short as possible but do not touch the flux-coating of the electrode into the molten weld pool. Hold the electrode at a 15º angle into the direction of travel. Stringer beads should be used in the flat, horizontal, and overhead positions. The weaving technique should be used for vertical welding but not to exceed two to three times the diameter of the electrode. Remove all SÜAg before making additional passes. On the final pass, allow the part to cool down partially before removing the SÜAg, then promote rapid cooling by quenching with a wet rag or compressed air. This will preserve the corrosion resistant properties of the 300 series Stainless. Do not allow to slow cool.
