The WRC-1992 diagram was not created in a vacuum; it is the culmination of decades of research. Understanding its predecessors highlights why it was such a significant breakthrough. This public link is valid for 7 days

Creq=%Cr+%Mo+0.7×%Nbcap C r sub e q end-sub equals % cap C r plus % cap M o plus 0.7 cross % cap N b

The diagram plots the on the X-axis against the nickel equivalent (Ni eq) on the Y-axis. By calculating these two values from an alloy's composition, a user can plot a single point on the diagram that reveals the weld's predicted ferrite number (FN) and its primary solidification mode, such as austenite (A), ferrite-austenite (FA), austenite-ferrite (AF), or ferrite (F) .

Using the , a co-driver could:

The calculator will plot the point and provide the estimated Ferrite Number, typically visualized on the WRC-1992 chart. Summary of Diagram Improvements Key Difference Limitation Schaeffler First widely used diagram. No Nitrogen, lower accuracy. DeLong Adds Nitrogen ( Nieqcap N i sub e q end-sub Limited to ~18 FN.

The calculator will plot these coordinates on the WRC-1992 diagram to provide: Typically
