General Description

AS SD-HSS is a basic coated electrode. It gives a Mo alloyed, high speed steel type weld metal. Deposited metal retains its toughness properties at high temperatures enabling the formation of high strength welds, particularly during the hardfacing of cutting and punching tools.  .

Applications

It is particularly used for hardfacing of cutting and punching tools made of alloyed and unalloyed steels with a hot tool steel structured weld metal. Part that is going to be welded should be preheated to 400-500°C and small beads should be preferred to inhibit overheating.

Machine tools, drilling parts, and tools made of high speed steels are among other application areas.
