Small hollow bar
Small hollow bar
(OP)
Hi.
I am after a hollow bar with about a 5mm bore and something around a 15mm OD.
Can anyone suggest who makes such a product as hollow bar stock?
Preferably in a higher grade than mild steel.
I am also looking for a steel rod in about 5mm that is not mild steel. Something like 4140 might work well.
I have run out of place to look .
Thanks in advance for any help you can offer.
Regards, Iain.

It is necessary to be careful with pipe, since there is a 12.5% tolerance on the wall thickness.
For the bar, the answer is much easier. Use drill rod of the appropriate alloy. If you do not have to weld it, O-1 is very versitatile and machines beautifully.

How many do you want to make/buy per day? Per hour?
How will you produce them? (Cut from a roll? Fed individually onto a lathe or mill? Feed as long stock that needs to be replenished regularly into a machinery line? Put together into a larger assembly?
What kind of finish do you need?
What are your tolerances on surface finish? Diameter? Source length and final cut length?
