The diagram plots the relationship between the and the Nickel Equivalent ( Nieqcap N i sub e q end-sub
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 wrc-1992 diagram calculator
Nieq=%Ni+35×%C+20×%N+0.25×%Cucap N i sub e q end-sub equals % cap N i plus 35 cross % cap C plus 20 cross % cap N plus 0.25 cross % cap C u The diagram plots the relationship between the and
To use the diagram, you must first calculate the equivalents based on the chemical weight percentage of the alloying elements: wrc-1992 diagram calculator
: Calculate the resultant weld metal composition based on the dilution ratio (typically 30% base metal and 70% filler for standard processes). Calculate Equivalents : Use the Creqcap C r sub e q end-sub Nieqcap N i sub e q end-sub formulas above for the final weld composition. Plot on the Diagram : Locate the intersection of your Creqcap C r sub e q end-sub (x-axis) and Nieqcap N i sub e q end-sub (y-axis) on the WRC-1992 Constitution Diagram .
