DeLong diag. for ph grades.
DeLong diag. for ph grades.
(OP)
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?

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.
