Online Engineering Tables

[SuperJake]

I'm trying to do an analysis of a frame in Pro/Engineer, and I need to enter material properties. No one in the office has an engineering handbook with the values I need, and even Google is having problems finding what I am after. I'm looking for the material properties of type 304 Stainless Steal (304SS). If anyone could point me in the right direction, that'd be great! Below is what Pro/E spit out at me...

Matweb.com (http://www.matweb.com) has properties for quite a few materials, including several types of 304 Stainless Steel from various vendors. I don't know if it has enough information for your purposes or not.

If you check the Pro/ENGINEER forums on mcad.com there is a file section that you can access with a free account.

They have a folder of material properties that you can import into your Pro/E.

EFunda: AISI Type 304 (http://www.efunda.com/materials/alloys/alloy_home/show_alloy_found.cfm?ID=AISI_Type_304&prop=all&Page_Title=%20Metal%20Alloys%20Keyword%20Search%20 Results)

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.

Thanks! These are really great refereces!
