The WRC-1992 diagram is the current industry standard for predicting the Ferrite Number (FN) and solidification mode of stainless steel weld metals. It improved upon earlier diagrams, like the Schaeffler Diagram, by including nitrogen and copper in its calculations, offering more accurate results for modern alloys. Key Formulas for Your Calculator
[ f_center = \fracf_low + f_high2 ]
To use the diagram, you must first calculate the equivalents based on the chemical weight percentage of the alloying elements: Chromium Equivalent ( Creqcap C r sub e q end-sub ): wrc-1992 diagram calculator
