MAG flux cored wire for heat resistant surfacings
on hot working tools
Application field
The metal powder flux cored wire SK D15-G is used for high stressed hot working tools, which are simultaneously
subject to abrasion, compression and impact. Main application fields are axial rolls, roll mandrills,
hot shear blades. The elevated temperature hardness (up to 550° C) and the abrasion resistance are
reached by addition of tungsten, molybdenum, chromium, cobalt and vanadium. SK D15-G is suitable for
the production and for the repair of high quality hot working tools.
Properties of the weld metal
The weld deposit of SK D15-G has a martensitic structure and may be machined by grinding.
Hardness of the pure weld deposit 60 HRC

Welding instruction
Clean welding area to metallic bright. Preheating temperature of 400° C on tools should be maintained. Slow
cooling in an oven or under a cover, tempering at 550° C, if necessary. Use neutral or slight pushing welding
technique. Pulsed arc improves weldability.
