Features :  1. High-carbon high-chromium steel type ledeburite2. Good hardenability and wear resistance.3. Modulizing softening annealing and good machinability4. Strengthening the added elements of molybdenum and vanadium.Applications :1. Used to produce more high wear resistance, impact load by the smaller cold mold, punch, cold cut scissors, drill sets, gauges, drawing dies, press die, drawing board, drawing die and die thread rolling die, etc. .2. High wear resistance, long life plastic mold.
