Description
 
Tool steel is to fabricate the cutting tool, measuring implement, mould, and wear-resisting tool, it possesses higher hardness and keeps maintaining the high hardness and redhardness under high temperature, and more abrasive resistance, proper toughness. Tool steel is commontly divided into carbon tool steel, alloy tool steel, high speed steel.  
 
Alloy tool steel is one type of steel adds the alloying elements in the carbon tool steel, such as Si, Mn, Ni, Cr, W, Mo, V. Adding the elements (Cr, Mn) can improve the hardenability of tool steel. Or adding other alloying elements meanwhile (the gross is not more than 5%).
Alloy tool steel is widely used to produce the cutting tool, cold/heat distortion mould and measuring implement. and further to manufacture the piston, valve, valve seat of fuel pump.

The alloy is usually produced by BEF & AOD followed by electroslag remelting (ESR) / VAR if necessary for special purpose.
Bars and, where applicable, forgings are subjected to ultrasonic examination based on the different levels according to the buyers' requirements. Bars are usually supplied black/bright in the annealed condition.
