I'm after yield and tensile strength charts for ERW and CDS tubing

[hough]

Can anybody please help, I'm trying to find charts to show the yield and tensile strength of ERW and CDS steel tubing preferably between 25mm and 42mm diameter tube.

 

[old-git]

There are lot of grades of ERW, ranging from 35-70000psi minimum yield and 60-82000psi minimum tensile strength.

This is even more so for CDS.

What are you planning to use it for?

It's for a set of girder forks and trike frame I'm building.

Main't the tube size I'm looking at is 32mm and 38mm or 42mm in wall thicknesses from 2.4mm to 6mm

Pedal or engined?

Don't know if this is of any use:
