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.

Paul,

   I'm just an amateur welder, but there's a web site with a lot of good
info for people like me called TIG Depot.  They have a one of the countries
top authorities in welding and metallurgy that is happy to answer questions
for the experimental aviation community (and racing community too.)  If you
don't find your answer in the FAQ's, you can email a guy named Wyatt Swaim
and he will get answers back to you.  The first link is for the shop, and
the second link is to a bio on Wyatt:  http://www.tigdepot.com/ ,
http://www.tigdepot.com/mrtig.html
   Perhaps this will be helpful to some of the guys.
