2,Production Process
3,Elemental Analysis of Finished Products
Carbon (C) : 1. Improve the deformation resistance and tensile strength of the blade;2. Enhance hardness and improve wear resistance. 
Cr (Cr) : 1. Enhance hardness, tensile strength and toughness;2. Anti-wear and corrosion. 
Cobalt (CO) : 1. Increase the hardness and strength so that it can withstand high temperature quenching;2. Used to enhance certain individual properties of other elements in more complex alloys. 
Copper (Cu) : 1. Enhance corrosion resistance;2. Enhance wear resistance. 
Manganese (Mn) : 1. Increase the quenchability, wear resistance and tensile strength;2.Removal of oxygen from molten metal by separate oxidation and separate vaporization;3. When added in large quantities, the hardness is enhanced, but the brittleness is improved. 
Molybdenum (Mo) : 1. Enhanced strength, hardness, quenchability and toughness;2. Improve machinability and corrosion resistance. 
Nickel (Ni) : 1. Enhance strength, hardness and corrosion resistance. 
Phosphorus (P) : Enhanced strength, machinability and hardness. 
2. When the concentration is too large, it is easy to crack 
Silicon (Si) : 1. enhanced ductility;2. Increase the tensile strength;3. Removal of oxygen from molten metal by separate oxidation and separate vaporization. 
Sulphur (S) : small amount used to improve machinability. 
Tungsten (W) : Increases strength, hardness and toughness. 
Vanadium (V) : Increases strength, hardness and seismic resistance.
