Product Description

alloy forged die steel round bar STD1

1. k100 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

2.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.
