III.Size:
| Round | Diameter | Length | |
| 10mm-600mm | 2000mm-5800mm | ||
| Steel plate | Thickness | Width | Length |
| 10-900mm | 180-2200mm | 1000mm-5800mm | |
IV. 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 plastic mould and can be operated by electric corrosion.
