GRINOX 310Mo

IDENTIFICATION : GRINOX-310Mo
CLASSIFICATION : AWS A 5.4 : E 310Mo - 16

DESCRIPTION :

An extruded, rutile based heavy coated electrode for welding 25/20 Chromium Nickel Stainless Steel.

WELDING PROPERTIES :

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 USES :

  • 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.

APPLICABLE FOR :

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.

Ferrite Number of the weld : O
