Cr12 mold steel Scope:
Cr12 is widely used cold work die steel , high strength , good hardenability and good wear resistance, but poor toughness . Mainly used for small to withstand impact loads requiring high wear Die and punch , cold cut scissors, drill sets , gauge, wire drawing dies , pressure die , thread rolling plate , drawing die and thread rolling die.

Cr12 belong to high-carbon high -chromium ledeburite also widely used cold work die steel This steel has good hardenability, wear resistance, hot workability. Carbides in the steel distribution is better, can be used to make complex shapes , a variety of cold mold under heavy working conditions such as die punch, thread rolling dies, drawing dies, die cutting , powder metallurgy die , woodworking cutting tools, drill sets and cold cut scissors and other tools to gauge .

Cr12 mold steel use:
Sheet thickness less than 2MM , efficient blanking die , punch die and pressure die . Scissors , inlaid woodworking blade . Thread rolling die and wear slider. Cold heading die , thermosetting resin molding . Deep drawing molding, cold extrusion dies .
