5.Applications

Suitable to make the punch dies or drawing dies which are complicated in shape and high in precision;Suitable to make the clid-work dies formed by linear cutting;Suitable high-speed punch head and cold forging dies;Suitable to make the blanking dies and punching dies with a thickness over 6mm.

Annealing	880~800°C, air cooling,  650~700°C slow cooling, hardness (255~207 HBS )
Hot treatment  quench	800--830°C, oil cooling, hardness ( ≥62 HRC )
Backfire (°C)	140-160°C,    170-200°C,    230-280°C
Hardness (HRC)	62~65         60~62          55~60

6.Delivery condition:

    Annealed + black/peeled/turned/grinding/polished surface upon customers' special request, UT test accord with SEP 1921-84 class c/c

7.Features

Toughness is 1 times higher than SKD11 cold rolled sheel. If used for fabrication of complicated punch dies and drawing dies, the resistance to crack and edge breaking will be highly improved.After high-temperature tempering of the die under 520-530°c, the hardness may still reach 60-62HRC, so that the risk of crack caused by residual stress will be reduced for linear cutting dies.Suitable for surface hardening treatment for extended service life of the dies.
