A WRC-1992 calculator works by converting the chemical composition of a weld (base metal plus filler metal) into two key values that are plotted on a 2D graph: Represents elements that stabilize the ferrite phase. Formula: Nickel Equivalent ( Nieqcap N i sub e q end-sub ): Represents elements that stabilize the austenite phase. Formula:
) using the weight percentage (wt%) of specific alloying elements: Engineering Stack Exchange Chromium Equivalent ( cap C r sub e q end-sub 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 Why Use the WRC-1992 Diagram? A WRC-1992 calculator works by converting the chemical
