Post by: sooty on April 16, 2008, 03:02 PM

Does anyone have or know of a supplier for small amounts of 4130 Chrome moly tube?

I have a 24" GT Santa ana that needs a new tube, the weldings no prob just want to get hold of the replacement tube.  :)

Thanks Soot.

Or try www.pfametals.com , they stock 4130. But be careful after welding coz it should really be stress relieved by heat treating correctly, or the area around the weld may be brittle (http://www.radbmx.co.uk/forum/Smileys/smilies/daumenhoch.gif)
