6. Applications:
Degree of hardness and the metallography structure are even, the cutting value and the polishing performance are outstanding, can be harden by flame, plates hardly chrome and nitriding. This mould steel can apply to general requirements of the size of the Cold work mould steel and can be operated by electric corrosion.
