Yield strength of deep drawn 304
Yield strength of deep drawn 304
(OP)
I'm looking for a representative yield strength for a deep drawn part made from 304L. I don't know the exact reduction yet as we are just in the concept phase. MatWEB gives values based on % Cold Rolled. Can I use these? I would expect the 20% cold rolled to be conservative (690 MPa). Also, MatWEB lists 0% cold rolled yeild strength as 290 MPa but annealed yeild strength as only 170 MPa. Is the 0% cold rolled still somewhat work hardened?

Looking at the range of strengths from 10% to 25% should give you a good picture of what you are likely to see.

RE: Yield strength of deep drawn 304
The hardening will depend on the local deformation. You can determine how much deformation you will get by looking at the thickness change in the section of the drawn part that's relevant for your purposes. 20% reduction should give you about a 300 to 400 MPa increse in yield strength, depending on alloy composition and drawing temperature. Interpolate from there.
