If you're doing Code work you're going to be using ASTM sooner or later. You'll find that the 'typical' properties for materials in matweb are generally optimistic, and they may involve thermal or strain hardening treatments not applicable to your work Strain hardened stainless steel is a good example. Great quoted mechanicals, but all that strength goes away if you start welding it. Like I said--be very careful out there. The words used to sell materials don't always translate very well into the properties you need to make practical use of them. There's a lot to be said for 'voluminous' ASTM standards, especially when it comes to getting a refund from a supplier who sent you a load of ferro-manurium instead of the structural steel you ordered.

Matweb is a pretty good guide and you can do a search on ASTM specs if you want--just do your homework.
