Steel for Fineblanking-Low Distortion
Steel for Fineblanking-Low Distortion
(OP)
I have an application for fineblanking a small part out of 9 gage (.149") carbon or alloy steel. The part is about .5x.7 inch with some precision holes and surfaces.
After the fineblanking process I want to heat treat the part to 55RC but I want to minimize distortion.
Any suggestions to my steel choice?
TIA

maybe try 4340 or something with a bit more carbon. (IS there a such thing as 4360?)

Since you are planning to use fineblanking, I think it would be best to investigate surface hardening. In order to quench and temper to that type of hardness, you will need a C content greater than 0.40%, which means that the flow stress is going to be quite high. Fineblanking companies are usually quite reluctant to form 3 mm thick steel with high flow stress. Good luck with your project.
