Thickness change from annealed to full hard?
Thickness change from annealed to full hard?
(OP)
Hi,
If I were to buy some annealed stainless steel and then cold roll it harder how would the thickness change?
What I want to end up with is 0.2mm stainless that is 2000N/mm2 hardness. So would I buy for example 0.4mm annealed?
Thanks,
Ant.

Often you are looking at 40-60% reduction in thickness to reach maximum hardness.
You do know that some of the PH grades can be made in the CH condition, where they are cold worked and then aged without annealing. You get some added strength from the cold worked condition. Look at 17-7PH.

I wish I'd seen Ulbrich's online shop a couple of months ago. Seeing that was a revelation and a pleasant change from the prices I've had recently. I will call them, there isn't any PH stainless in the online shop but the prices give me confidence a special order wouldn't be too expensive.
Thanks.
