Product Description
Tungsten carbide is one of the best materials with its highest hardness,wear resistance material in the industrial except diamond.
HF WC is a nickel cored flexible rod coated with mainly spherical fused/cast tungsten carbide and Ni-Cr-B-Si-Matrix. The hard facing is highly resistance to acids,bases,lye,and other corrosive media and excessive wear conditions.It can be covered on the carbon steel,low carbon steel,low alloy steel,stainless steel,cast iron and ductile iron surfacing, suitable for oil drilling tools (such as PDC drill,Centralizers),building machinery (such as the blade of brick and concrete production),mining geological tools,agriculture,food and chemical industry machinery.It is mainly used for surfacing and repairing for the strong wear and tear corrosion part,can significantly reduce tool wear and tear,improve work efficiency.The rod has a low mlting range of between 950-1060 �?? and feature a self fluxing characteristic producing a smooth,clean welded surface.
Application:
Hard facing on ferritic and austenitic steels(steel castings),over-laying mix ed blades,screws and conveyors in chemical,dye and food industry.
Specially recommended for stabilizer blade in the petroleum industry.
HF WC-S can hold the higher load wear,
higher resistance to high stress and high stress wear.HF
WC-S particles mainly is spherical casting WC particles
and irregular casting WC particles,sepherical cast tungsten
carbide particles have good toughness and strength binding
with the metal,supplemented by a certain amount of irregular
casting carbonization,so that the surfacing layer has a better
wear resistance and impact resistance.The actual thickness of
surfacing electrode, different diameters can be choosed accor-
ding to the tools demand,generally covered 1 to 3 layers.
Application:
Hard facing on opetroleum industry tools(PDC,stabilizer blade),ferritic and austenitic steels(steel castings),over-laying mixed blades,screws and conveyors in chemical,shredding machine,mining scraper, mud pump blades, drill pipe joints, centralizer, mining cut Teeth, cone and so on.
HF WC-C is suitable for low stress wear conditions,with a
higher resistance to low stress wear.HF WC-C mainly
filled with irregular casted WC particles. The hard particle
size designed optimization,which blend different particle
size very well.
In the process of welding hard particles are closely,so improve
the wear resistance and impact resistance of the surfacing layer.
Application:
Hard facing on opetroleum industry tools(PDC,stabilizer blade),shredding machine,Turning machine,drilling rock machine,mining scraper, surfacing and repaired mud pump blades, drill pipe joints, centralizer and so on.
