DeLong diag. for ph grades. 1

[rayband]

Once upon a time I had a copy of a modified DeLong diagram (chrome equivalent vs nickel equivalent) that mapped the PH grades of stainlesses. I have lost the copy and cannot remember or find the reference. Can anyone help here?

I'd like to see that one, too.

The only diagram I had seen that was similar to a Delong diagram for PH stainless steel was listed in a book that I had recently used to look up some information on an unrelated topic. The diagram could only predict solidification mode and not final weld metal structure.

The diagram is from the Welding Research Council, WRC-1992, and shows the Ni and Cr eqiv's modified with Al and Ti coefficients for 630,631, and 13-8 Mo PH. The reference is "Welding Metallurgy and Weldability of Stainless Steels" by Lippold and Kotecki, and the diagram is on page 277.
