Welding electrode for 304 stainless steel – Available in 2 and 2.5 mm | Packs of 20 units

Supranox RS 308L Electrode: Professional Welding for Type 304 Stainless Steel

The Oerlikon Supranox RS 308L electrode It is the benchmark solution for professionals who demand precision, durability and impeccable aesthetics in welding. austenitic stainless steels type 304 and its variants. Thanks to its advanced formulation, this coated electrode offers superior operability in both workshops and demanding industrial assemblies.

Available Models

• Diameter 2.0 mm (Pack of 20 units): Excellent for small welds, thin-walled pipes, thin sheets, and outdoor craft pieces requiring a discreet, precise, and polished seam. Available in 300mm length.
• Diameter 2.5 mm (Pack of 20 units): The ultimate all-purpose diameter. Recommended for intermediate thicknesses, structural connections, heavy-duty outdoor fixings, and industrial equipment that must withstand combined mechanical and environmental stresses. Available in 350mm length.

Low Carbon: Maximum Resistance to Intergranular Corrosion

One of the biggest challenges when welding stainless steel is carbide precipitation in the heat-affected zone (HAZ). The formulation with low carbon content (308L) Supranox RS effectively reduces this risk, preventing intergranular corrosion and ensuring that welded joints maintain their structural properties and service life intact, even in the most aggressive environments.

Technical characteristics

Superior Operability and Aesthetic Finish

Forget about laborious post-welding processes. This electrode stands out for its easy priming and an exceptionally stable bow, This allows for complete control over the weld pool. The result is clean, uniform weld beads with minimal spatter, drastically reducing cleaning time and providing a visually perfect finish.
