Recently, we are building a tool with a long sliding rod size D=10.00mm, length=220.00mm,which is engaged in side sliding insert as a seal off contact, see attached picture,the original steel chosen was H-13,after reviewing the tool drawing specifically, we released the H-13 with 56HRC might iccur breaking easily,then we come up with another option maybe Moldmax will be a favorable replacement,here comes the problem, the diameter is 10.00 mm with 6.00mm cooling line within, which means the wall thickness will be 2.00mm, which caused a milling issue.the rod is 220.00mm, which make it hard make it.then we thought anther steel S136H, which is a pre-harden steel with high tenacity, what do you think?
I just found those DME cooling components are greatly useful in a small and long insert rod.
Here comes the T1 samples.
