HI guys.
Does anybody have any info on what type of steel used for k11 frame production?
It looks to me like regular mild steel, but I just want to be sure.

Thanks.

There's not much to read in this thread but I think it's as close as it gets at the moment.

but maybe you could pm Gui and find out from his mechanic any info that would help.

It's certainly not 1020 mild steel. It's more like an aircraft steel called 4130. . Maybe not such a high quality but still much better than MS. I have just sawn all the brackets off the rear frame and it certainly behaves like 4130 chrome moly. if you need any it's pretty easy to get.

Thanks a lot. Sadly it's not that easy to get 4130 in my location.

So where are you? In the U.S. the supplier is Aircraft Spruce. Do you need tube or sheet what sizes? I have a small selection of sheet and tube. You could substitute CDEW tube (cold drawn electric welded) tube.....

I'm from Taganrog, Russia.
The most funny thing is I'm near by tube-rolling shop. But they just didn't produce thin-wall chromoly tubes.
