2. Delivery Condition:

1. Hot rolled , black,

2. Hardness: HRC=28--33,

3. Annealed Hardness: HBS<=235.

 

3. General

   Good mechanincal property, make surface have equal hardness after deal with it; Nice polishing , mini. roughness on the surface, deal with induration in advance. It can used directly after the mould mould machined, deal with surface induration necessity.

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 plastic mould and can be operated by electric corrosion.

7. Payment: 30% deposit, balance against T/T or L/C at sight.
