HRF 10 (For super high wear-resistant):
Ultra micro-grain quality carbide is ultra high wear resistant, but less impact-resistant.It is applied in mid and low speed light cutting of
 various materials that require ultra high wear resistance. Generally, it is applied in good work condition, stable cutting, good part fixture and
 continuous light-duty machining. Comparing with general tungsten steel, it has 3~5 times more life time. Conforming to ISO K10~K25/P10~P25.
VRA201: Imported ultra micro-grain quality carbide, with excellent impact-resistance and general wear-resistance. Generally applied in worse or general equipment to machine materials of lower hardness HRC≤25°, discontinuous cutting and worse part fixture. Conforming to ISO K25, can replace machining of materials like M42, ASP60, MPM, HSSCo10 etc, and can get 4-6 times lifetime, it has higher performance/price ration. Comparing with SKH51, it has 15-25 times lifetime and durability.
HRF10: ultra micro-grain quality carbide, has excellent wear resistance, but its impact resistance is not so good. It is applicable for medium and low speed cutting of high hardness materials(HRC45°-65°) requiring thermal refining and quenching or for various materials having higher wear resistance and non-ferrous metal. Generally it is applied in good working condition\stable cutting\excellent part fixing and continuous light machining. Corresponding to ISO K10.
ASP60C :
mported ultra high wear-resistant high-grade high cobalt powder steel, quenched:HRC70°±2°, with excellent wear resistance and impact resistance. Comparing with HSSE\HSS-AL and HSSCo, it has 4~8 times lifetime, and can guarantee uniformity and conformity rate of machined products. It is often applied in general equipment for machining various materials including Ni\Cr\Mo\Si\Ti) that are hard to machine like high alloy\heat-resistant alloy\cast iron of nickel-vanadium-titanium alloy\stainless steel. It is excellent machining tool before heat treatment. It has excellent high temperature machining and comprehensive performance, and allows higher cutting speed. The higher the hardness of machined materials, the more remarkable the effect. Because its roughness is not so good, it is not suitable for discontinuous cutting or for using under processing system of insufficient rigidity, otherwise, cutter will be hit or chipping will happen.
PR40
super micro-grain diamond tungsten steel, extensively applied, it can be applied in medium speed cutting and finish cutting of various materials with HRC28°. It has excellent impact resistance and general wear resistance, and has extensive application. Generally, it is applied for thicker cutting, discontinuous cutting and bad part fixture. After being coated, it has better result, can machine various materials of HRC50°. Comparing with ISOK20&general tungsten steel, it has 1-2 times lifetime and excellent wear resistance
