COSMAX – 310

Classification : AWS :E310-16 , IS 5206 :E25.20R16

Characteristics : A medium heavy coated, stainless steel electrode depositing 25 Cr, 20 Nl, In weld metal. Metal possess excellent mechanical properties and resists scaling at high temperatures upto 1200°C. Low spatter loss, smooth and uniform bead having easy slag removal properties.

Applications : Ideal for welding similar stainless steel in wrought and cast form. The electrode is also suitable for dissimilar steel welding and also for welding of hardenable steel, clad steel, chamber parts, annealing boxes and carburising pots, C-Mo, Cr-Mo steel where high preheat and PWHT are impractical.
