GRINOX 18 E318-16
AWS/SFA 5.4: E 318 – 16 IS: E 19.12.2 Nb R 26
An extruded, rutile based heavy coated all position electrode for welding 18/8/2 Chromium Nickel Molybdenum stabilised Stainless Steel.
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 & porosity. The weld bead is finely-ripple, smooth and regular. Due to stabilisation with Columbium, the weld deposit has increased resistance against Intergranular Corrosion and excellent creep strength upto 850°C.
