P20Alloy Round Bar GB 3Cr2Mo 1.2311
2. Delivery Condition:
1）. Hot rolled , black,
2）. Hardness: HRC=28--33,
3）. Annealed Hardness: HBS<=235.
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.
4. Chemical analysis
Chemical composition(for reference only):
5. Compared grades(based on usage)
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.
