Wrc-1992 Diagram Calculator Now

WRC-1992 diagram (Welding Research Council) is a standard constitution diagram used to predict the Ferrite Number (FN) and the final solidification mode of stainless steel weld metals. It is widely considered the most accurate manual method for copper-bearing stainless steels and duplex stainless steel welds. Welding Knowledge

The diagram uses two "equivalents" calculated from the chemical weight percentage of the alloying elements: 1. Chromium Equivalent ( cap C r sub e q end-sub

[ FBW = \fracBWf_center \times 100 ]

This represents the combined effect of elements that stabilize (the magnetic, crack-resistant phase). Formula:

The WRC-1992 Diagram Calculator is an indispensable utility for welding engineers, inspectors, and metallurgists. It replaces estimation with precision, ensuring that welding procedures are optimized for chemical composition before a single weld is laid. By validating that a filler metal and base metal combination will yield the correct Ferrite Number, the calculator serves as a frontline defense against costly weld failures. wrc-1992 diagram calculator

coordinate system to plot the position of the weld matrix on the WRC grid: : Chromium Equivalent ( Creqcap C r sub e q end-sub ) typically ranging from 17 to 31. Y-Axis : Nickel Equivalent ( Nieqcap N i sub e q end-sub ) typically ranging from 9 to 18.

High ferrite levels can cause low-temperature embrittlement in cryogenic applications. The WRC-1992 Formulas

For dissimilar metal welding, you can input the dilution percentage to see how the base metal affects the final weld composition. Chromium Equivalent ( cap C r sub e
