Mechanical Properties of AISI 304 and 316 Stainless Steel

[sloth4z]

I am looking for the yield strength of AISI 304 and 316 stainless steel.

AISI 304 seems to yield at around 30,000 psi (according COSMOSWorks, Matweb, and Efunda). I am inclined to believe this is a good number as all three suggest a yield strength about the same.

AISI 316 has a different value depending on where you look.
Efunda -> 29733 psi (converted from 205 MPa)
Matweb -> 42100 psi (for sheet)
-> 36300 psi (for plate)
COSMOSWorks -> 25000 psi (for sheet)

I also have a MTR that lists the yield strength at 51600 psi. It is for 316L which I am told is the same thing. According to my supplier, they use a material that meets the requirements for both (316 and 316L).

I am trying to figure out which one to use. I would like to use the one with the higher yield strength.

Well it all depends. If you doing a design then you need to use the specification minimums, since you could actually get that.

For 316L most product forms have a 25000psi min yield. You can see material as high as the mid-50's.
