3,Tchnics:negotiable on fabrication processing with price
4,Specification:possessing outstanding feature of high hardness,wear resistance,hot hardness,the hardness wont decline when the temperature between 500 and 600.It can be used in high speed cutting and manifest better ability than low contant alloy cutter.
5,Application:cutters in high speed,heavy load,high temperature.eg:turning tool,milling cutter,hobbing cutter,planing tool,broach,aiguille,screw tap.Also can be used in making mould,high temperature spring,high temperature bearing meet with high wearing resistance requirment
