Oerlikon Supranox RS 307 description: SUPRANOX RS 307 is a rutile-coated MMA electrode suitable for joining, buffering, maintenace and repairing. Used for difficult-to-weld steels and austenitic-ferritic, dissimilar steel, joining as well as hardfacing, buffer layer and for joining manganese hard steels, e.g. X120Mn12. The weld metal is highly crack-resistant and non-scaling < 850C. The hardness of the all-weld metal is 180 HB which works hardens up to 300 HB under impact loads. Highest operating temperature for dissimilar steels joints is 300C, above, SUPRANEL 182 is recommended. Stainless, fully austenitic chromium-nickel-managanese weld
metal, small amounts of delta ferrite are possible. Excellent weldability with a spatter free arc, self-releasing slag combined with a very smooth bead appearrance.
