AN EXTRUDED, MEDIUM-HEAVY COATED, HARD FACING ELECTRODE.
IDENTIFICATION
Gridur 350
DESCRIPTION
An extruded, medium-heavy coated, hard facing electrode. For building up the parts, not more than 3 layers of deposition should be made. If more layers are required, an inter layer with GEECON PURPLE is recommended. A buffer-layer with GEECON PURPLE is recommended for application on high carbon steel or hard base materials.

WELDING PROPERTIES
• Striking and restricting properties are good. The arc is stable and the slag is easy to remove.
• Weld metal surface is smooth and shows fine ripples.
• Weld deposit is machinable.
TYPICAL APPLICATIONS
• Impact and Abrasion resistant hard facing of machine parts made out of mild steel, structural steels and cast steel.
• Rails, couplings, rollers, pulleys, wheel rims, conveyer screws, axles, shafts, hammers etc.
APPLICABLE FOR
• Impact and Abrasion resistant hard facing of machine parts made out of mild steel, structural steels and cast steel.
HARDNESS OF WELD METAL
325-400 BHN, depending on parent metal and welding conditions.
