| Application and Properties: |
|
Flexible rod for hard
surfacing by oxy-gas welding. Consists of a small
diameter pure nickel core wire thickly coated bu
tungsten carbides in a Ni-Cr-B-Si matrix. The weld metal
is a heterogeneous metal composed of tungsten carbides
distributed in a hard and tough matrix. Shows extremely
high abrasion resistance. It has got a quiet melting and
good wetting. Especially used for hard surfacing of
mixers, crushing mills, die blades and heads, sand
foundary equipment, drilling tricones. |
