ASTM A513

[AUCE98]

Does anyone have experience with substituting ASTM A513 square tubing for ASTM A500? ASTM A500 is recognized in the AISC as well as AISI Cold-formed Steel Design manual, and is typically what is specified for structural applications. The issues that I am aware of are the low carbon content in the A513; therefore requiring the welders to be certified as well as the nominal dimensions are slightly different from A500 shapes. Additionally, I have assumed the yield strength to be FY=50 ksi as a conservative number rather than fy = 86 ksi. Has anyone had experience in using this as a structural element?

I'm not sure where you are working, but in every part of the US that I know of, all welded structural components must be welded by certified welders, whether A500, A513, A36 or others. The difference in this case is that the material might require a special procedure or special filler metal that takes is out of the realm of a pre-qualified welding procedure specification.
