Surface Finish Requirements 12-16uinch
Surface Finish Requirements 12-16uinch
(OP)
I need to have a 3/8" round bar finsihed with a surface finsh of 12-16 microinches. Is this something that is going to be achievable using 8620 or 4340 without being heat treated and being ground. The part would be machined on a lathe.
Is there a rule of thumb on what surface finish is possible according to the hardness. Or are the two related?

Could you start with a TGP bar like Mirraloy from Associated Steel. We used this material in place of a 4140,4130,3140, along with 4340 on some parts.
