Process order of a 316L stainless steel component
Process order of a 316L stainless steel component
(OP)
Hi Folks,
I am currently liasing with a supplier on the manufacture of a small (25mm X 25mm X 1.5mm)316L stainless steel component.
The component has a Pierce & extrude slot feature which extrudes through 1.8mm (material thickness 1.5mm). Component is cold-worked.
The supplier is currently annealing (for stress relief of the cold working process), then deburring.
Basically my question, is it common to anneal then deburr? If it was me doing this i would deburr then anneal.
It probably does not make much difference in this case, however i have doubts over the competence of this particular supplier hence why i am scrutinising everything they are doing.
All replies welcome.
Gareth

The other potential benefit to follow anneal first, then slitting, deburring is to get rid of pull under width issue which could occur during the strand annealing.

There is no stress relief of SS, you either anneal or you don't.
If you deburred the 'hard' part you would be less likely to deform the part and you may be able to used a process like vibratory abrasive deburr.
If you anneal first then you may get nicer blending of the edges and a better overall look, and maybe a chemical assisted deburr would work nicely.

We found stress relieving was not effective for austenitic SS at <1000F, while martensitic and ferritic SS responded better. This seemed to be related to dislocation movement. It is off the topic, but could you know the reason(s)? -Thanks!
