Paul,
I was wondering if you or anyone could tell me if there exists a stainless
alloy that would be equivalent to 4130?
Thanks

First I don't know what you mean by equivalent.
Second I am no metallurgist :)

Good point, Paul.
If you are considering a welding alloy,
stainless is acceptable.
Check the Lincoln website for specifics.

Thanks Everybody,
I was wondering if there might be a suitable substitute with the scarcity of
4130.
Thanks
Dean

If it calls for 4130 there are few if any options. 4130 is resistent
to fatiqe so that is the main reason for using it in aircraft.
It also depends exactly how and where it is being used.
