Chuck,
we, the frequentors of this site, don't know each other personally, but over the years of exchanging ideas and experience in welding, have become friends, havn't we?
I'm very sorry about your father and hope him a prompt recovery. I'll remember him in my prays today. You see, I believe that religion and science are not opposite nor incompatible, as others do, and so I consider myself a religious person.
As for Richard's question, I remember that L type stainless steels, more expensive to produce than plain ones, were developed exactly to solve the problem of welding difficulties due to sensitization. Therefore, in my opinion, Richard can have pleasent dreams.
