Using the correct grade steel
I have one of the rally design splined steering shafts and need to cut an extend it. What steel tube should I use to do this. Wall thickness and steel
grade?
Also need to make some engine mounts and I would like to make them tubular so again what material should I use?
thanks

steering - 4-5mm thick
mounts - 2in tube 2mm thick
grade - should rust, not that important so long as it's thick enough
you can tell by the long gap before anyone answered this that no one has the faintest idea of the grade their using, 'but I just found it in the
scrap skip!'.

You forgot to mention if the tube should be seamless or ERW
Seamless tube would be the strongest. Any grade seamless should do. Cold drawn that is. !!??
It,s nice to know we have at least one person on the forum that has a working knowledge of steel.

MILD STEEL eg. plain oridinary low carbon general purpose structural steel.
Use anything else and you could end up with failed welds.
If you weld higher strength steels you would need to heat treat the part --- no big deal for a small part.
