K100 method for the purpose and use a high chromium high carbon steel, cold high abrasion resistance and corrosion resistant performance, more candle with high hardness.

U adopts vacuum refining processing properties, Adopts of ball annealing softening, machining performance is good, Responding to GaoShiYi hardness, electricity, strong acid, alkali Responding to the long-term production with no deformation of steel.

Mainly used for u USES stainless steel chips cut second-ranking mouth XiGangPian dies, mould and deep cut mouth, Responding to make cold mould, main mode, laguan.

Also used in making cutting adopts a knife and cutting tools as template, screws, Painted steel factory second-ranking state of ball annealing hb250 painted using method adopts normally use hardened piece. It + took for precision dimension using quenching + to + tempering "painted steel stress and temperature responding to 10.5 degrees began forging, until 850 ° c forging furnace slowly with cold.
