Oerlikon Supranox RS 318 description: SUPRANOX RS 318 is a rutile coated MMA electrode for welding similar stabilised austenitic stainless, Cr-Ni-Mo steels and cast steels. Structural works with similar stabilised stainless steels. Applications include wet-corrosive conditions for operating temperatures <400C. The weld metal transfer is in fine droplets, nearly spatter free with a generally self-releasing slag, producing finely rippled concave fillet welds with an outstanding weld bead aspect. Good striking and restriking.
