GRINOX 47H E347-16
AWS/SFA 5.4: E 347-16 IS: E 19.9 Nb R 26
An extruded, rutile based heavy coated electrode for welding 18/8 Chromium Nickel Stabilised stainless steel type AiSi/ASTM 321 or 347 grade.
Weldable in all positions. Arc striking and re-striking properties are excellent. Arc is soft & stable. The spatter is very low and the slag is easy to remove. The weld deposit is free from cracks and porosity. The weld bead is finely- rippled, smooth and regular. Due to stabilisation with Columbium, the weld deposit has increased resistance against intergranular Corrosion.

MECHANICAL PROPERTIES (RANGE)
For welding stainless steels type 321, 347, 304. Also for surfacing unalloyed, low alloy and cast steels, Food Stuffs, Dairy, Textile, Chemical & Aircraft Industries, Household appliances, pipe-line figgings, Hospital Apparatus, etc.
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. Maintain interpass temperature 150°C max. Redry electrodes if required at 200°C for one hour.
