Note: The Schaeffler diagram predicts weld metal microstructure for dissimilar joints. It does not account for nitrogen - use DeLong or WRC-1992 for nitrogen-bearing alloys.
Reference
Schaeffler Diagram Equivalents:
Creq = Cr + Mo + 1.5×Si + 0.5×Nb
Nieq = Ni + 30×C + 0.5×Mn
Diagram zones: A (austenite), A+F, A+M, A+M+F, M, M+F, F
Used for dissimilar weld microstructure prediction since 1949.
