Metric tubing in the UK?

Could someone check for me- Looking for some chromemolly tubing in metric sizes. Specifically 20mm or 25mm OD with a 2mm wall thickness about 1 meter long - sources?? I can't find any metric tubing over here at all. Inch sizes only in the USA.
 
Hi Tillerman6, Chromemolly specifically 4130 in USA (expect imperial sizes) is eqivalent to UK spec. 708A25, 708M25, CFS10. Italian spec. 25CrMo4 (hopefully metric).

Switching search from 4130 to (708M25) gets you to 25CrMo4 stuff, here is a link example.

Just a by the by, 708M25 I hardly came across, more likely 708M40 EN19 for large shafts, available and requested in my day in engineering.
Try T45 too, managed to buy that in 45mm dia tube.

Can see 20mm x 1.83 wall.
But I hope it helps. Sorry not to find specific places for purchases but I'd be here all day! Twas my job at one time, now retired.
Have fun.
Martin.

Martin- Thanks for the info! I had no idea who made this in metric sizes and the only front hubs available are in metric sizes only. This should help a lot if I get back on my tadpole trike project I will contact this company and see if they can sell a small quantity to someone in the USA. Meanwhile I'm starting a new Delta trike with the help of my new evolution R255 metal cutting miter saw.
 
While searching for specialist items, came across this for you, 25mm x 1.2mm and lots of other metric sizes. Might be close enough.

Just checked properly and discover it's not metric. Bad description....

Chromoly round tube 25 x 1.2mm
Aircraft grade chromoly round tube. Priced per metre. Can be cut to length. Transport costs are dramatically reduced if the supplied length is 2m or less.

Outer Dimension: 25mm: 1″

Wall Thickness: 1.2mm

So it's 1".....

Depends if that 0.4mm matters!

Martin (again).
