M238

由于增加1.1%镍，因此淬透性{jj0}，

钢材表面至中心硬度均匀一致，放电加工性能好，令加工面组织细光洁，免除开裂风险。抛光性能和光蚀性能甚佳，适合氮化，镀硬铬和物xx相承继等。

Because of the Ni-addition ,there is no hardness decrease in the centre even for large sizes.Good EDM properties reducing the risk of cracking during peoduction.Optimum polishability and photoetching properties suited for nitrding,hard chromium plating &PVD coating.

适用于塑料加工的厚膜（厚度超过400mm）塑料模的模架

Larfe moulds (over 400mm thinkness) for plastic processing,mould carrier frames for plastic moulds.
