An extruded, rutile based heavy coated electrode for welding 25/20 Chromium Nickel Stainless Steel.
Weldable in all positions. The weld bead is finely-rippled, smooth, and regular. The deposit is highly resistant to cracking. Scale resistance upto 1000oC. The deposited weld metal is of radiographic quality.
Highly stressed corrosion-resistant Stainless steel containing about 25% Chromium & 20% Nickel. Also for Stainless Steel AISI grades 309 & 310 and clad steels. Also used for joining dissimilar steels, straight Chromium Steels, welding intermediate zones between mild steel and Stainless Steels, joining difficult alloy/High Carbon Steels.
The base metal should be free from oil, Grease or Dirt before welding. Keep a short arc- length. The weld bead should be cleaned with stainless steel brush.
