The United States air cold hardening type hot work die steel, the
steel is the three most common hot die casting industry in Europe
die steel, carbides, steel distribution, hot crack resistance and
anti corrosion performance, and good processing performance, good
hardenability, temperature with thick heat and force in the
oxidation resistance, high toughness and wear resistance.
