The margin of the material must be as twice as the practical material to use, if you need the material forged to be ideal crystal compactness, and long time wear-resistance of the edge and the sharpness. That is to say, the raw material *πR2 *thickness*density*2 times*unit price, that equal to the actual cost of material to use after forging.

HSSE: (The widely using ultra hard type)
Ultra hard exclusive high speed tool steel, hardening at HRC63 ± 2degrees. Corresponding HSS has even more ideal wear-resistant and service life
SKH51A/M2：( The widely using ultra hard type )
Ultra-hard high grade powder high speed tool steels, quench-hard treatment HRC60°~62°, Comparing with HSS, it has more idea lifetime and excellent wear resistance.
SKH55A: (Special Hardness)
Special hardness high Cobalt powder steel, Quench treatment HRC65°±2°（HRA82°-84°）, Moreover HSS have above 2-3time use life. Correspond to ISO M35A.
SKH57A: (ultra hard)

quench hardening at HRC67°±2°（HRA83.3°~85.6°）, comparing to HSS it has 2~4 times or more longer service life .
SKH59 :( ultra high wear-resistance)
Imported super wear-resistance high grade high cobalt powder steel: hardening at HRC68.5°±2°,with excellent wear-resistance and impact-resistance compare with the material of HSSE、HSS-AL or HSSCo, with more than 4-6 times serving lives, and we are sure of the uniformity and percent of pass of the material to machining. which usually machining various with high temperature alloy by common machine, and heat resistance , Nickel alloy cast iron vanadium, and stainless steel, for these hard to machine materials (contain nickel,Cr, Mo,Si,Ti,)and most excellent machining tools before heat treatment. It is machined with high temperature and comprehensive ability, and high cutting speed allowed, the performance would be better if the hardness of the material to use is higher. Owing to the bad tenacity, and it’s not suitable for using under non-continuous cutting and the condition of worse steel feature, it would be easy to tipping,!
ASP60C:
Imported 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 are, the more remarkable the effect would be. 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’s hit or chip will happen.
