A513 Mechanical Tubing

[AVak]

I have a contractor that wants to use ASTM A513 mechanical tubing for sub-framing between open web joists. In order to check the design I need to know the yield strength of this material. Does anybody know what it is?

I am sure you can google it as good as any of us.

It depends on the specific grade specified in A513. Values vary from 23 ksi to 100 ksi depending on composition and whether it is "as-welded", "normalized", "sink-drawn" or "mandrel drawn".
