TYPICAL APPLICATIONS
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.
TYPICAL APPLICATIONS
• For joining the above heat resisting steels and also for surfacing unalloyed, low/high alloy and cast steels. Furnace fabrication, apparatus, steam boilers, piping & fittings, textile, paper, paint, rubber and glass industries, heat treatment shops, gas turbines, oil refineries, furnace fabrication, etc.
• Overlay on castings.
• Welding of heat resisting castings.
• 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.
WELDING PROCEDURE : 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.
