GEMET 315

Electrode for surfacing of high speed steels
PROPERTIES :
Basic coated electrode with excellent properties. The deposit is high quality tool steel. Tough, hard wear and oxidation resistant, free from cracks and porosities.
TYPICAL USES :
For the repair and manufacture of cold and hot cutting tools, trimming knives, broaches, punching tools, drills, milling tools, hot dies, forming dies, ingot lifting tons etc.
Alloy basis : Cr, Mn, Mo, W, V
Hardness :
As welded: 59-61 RC
work hardened: 62-64 RC
PROCEDURE:
Preheat larger and intricate section between 300-600° C and maintain the same during welding. Smaller jobs need not be preheated since the arc temperature does the needful. Chip slag between beads and peen to reduce residual stresses for heavy deposits. Slow cool the job using an oven or asbestos.
