Cold work tool steel din
1. Grade: AISI:D3 ,DIN:1.2080, JIS:SKD1,GB: Cr12
2. Process: EAF+LF+VD+ Forged+ Heat Treatment (Annealed,A Normalized, Q+T)
3. Technique: Hot Rolled
1. Cr12 round tool steel
2.Cr12 steel is a widely used cold work die steel, a type of high carbon high chromium ledeburite. The steel has good hardenability and good abrasion resistance
3.Mainly used to with stand the impact load is smaller, and require high abrasion resistance Die and punch, cold-cut scissors, drill sets, gauges, drawing die, pressure die thread rolling board, drawing die thread rolling die.
