I got a 10 ft section of 1"x.188 tubing for free.
Can it be welded if so with what?
Can it be tapped?
I would like to use it for trailing arms if it is suitable.

Thanks

That's awfully thick for Chromolly. You could use mild steel and it wouldn't need to be that thick.

don't know anything about it except you got it for free. makes its use a bit more desirable than going out and buying something else.

it is not chromoly its brandname is croloy looks to be the right size to tap for the trailing arms using 3/4 rod ends I would like to find out its properties basically to make sure it is not to brittle

everything associated with croloy seems to have to do with heating/cooling pipes from a few search's.

yeah I still cannot find much info about it. I tried to drill it out and to tap it but was unable to get very far. seems to be really hard stuff

I found a heat exchanger paper that listed the basics for croloy 2 1/4. It is very high yield, which usually corresponds to brittle.

It appears to be in the family of stainless, which makes welding somewhat interesting, certainly not for the faint of heart, nor inexperienced.

Google "croloy modulus" and "croloy welding" and it looks like the actual alloy makes a big difference for weldability. If you don't know what exactly you have don't try to weld it.

I would be concerned that by cutting threads you could be asking for a brittle fracture problem if you live in a cold climate, but that is just based on knwoing conerns for nuclear power plants using similar materials...
