Re: [PSUBS-MAILIST] hatch rings

["Brian Cox" <ojaibees@ojai.net>]

I contacted Inco about Monel, the guy I talked to was very friendly and steered me to Special Metals of West Virginia.  He was telling me that there is mig wire that is specifically made for doing overlays but he wasn't sure exactly what alloy would be appropriate for my application.  I have an e-mail into Special Metals with the question.  When I get a response I will pass it on.
