TYPICAL APPLICATIONS

GM ST6 is used for high - grade hard - facing on parts subjected to a combination of erosion, corrosion, cavitations, impact, pressure, abrasion and high temperatures up to 900°C, such as tight surfaces on fittings, valve seats and cones for combustion engines, gliding surfaces metal - metal, highly stressed hot working tools without thermal shock, milling mixers and drilling tools. Excellent gliding characteristic, easy polishability, good toughness, nonmagnetic, machining by grinding or with tungsten carbide cutting tools.

WELDING INSTRUCTIONS

• Clean welding area
• Preheating temperature 450 – 600°C
• Very slow cooling
• Hold electrode vertically and with a short arc and lowest possible amperage
• Re-dry electrodes that have become damp for 2h / 300°C

SHIELDING GAS : 80% Argon + 20% CO2
