EFunda: AISI Type 304
That should be most all you need. Shear modulus could be calculated, but you can probably leave it blank. The tension and compression stresses are defined by you, really. Typically you design to yield as a first iteration. Shear limit can be calculated as well. Emissivity doesn't matter unless you're doing thermal modelling, and even then is highly dependent on surface finish. Condition probably doesn't matter, nor should anything below it.
