IDENTIFICATION
Gemet 3200N

DESCRIPTION
Basic coated, low hydrogen electrode depositing weld metal which is well suited for highly abrasion resistance application. The weld deposit is high quality tool steel which is tough, hard, wear and oxidation resistance.
ALLOY BASIS : Mo, Cr, W, V, C

TYPICAL APPLICATIONS
For manufacturing new cold & hot working tools, hot cutting tools, trimming knives, cold punching tools, valves, extrusion press pistons, forging tools.

HARDNESS OF THE PURE WELD METAL: As welded 59 – 62 Rc
AFTER WORK HARDENING: 62 – 65 Rc

WELDING INSTRUCTIONS
•    Redry electrodes at 300ºC / 2 hrs. before use.
•    Preheat the workpiece to about 400ºC
•    Hold electrode as vertically as possible and with a short arc,                 deposit welds. Allow the workpiece to cool slowly.
•    Finish by grinding
