The (officially titled "WRC-1992 Constitution Diagram for Stainless Steel Weld Metals: A Modification of the WRC-1988 Diagram") is a predictive metallurgical tool developed by Damian J. Kotecki and Thomas A. Siewert, and published in the Welding Journal in 1992.

The WRC-1992 diagram maps the balance between ferrite-promoting elements ( Creqcap C r sub e q end-sub ) and austenite-promoting elements ( Nieqcap N i sub e q end-sub

The is the industry-standard constitution for predicting ferrite content in stainless steel welds . Developed by the Welding Research Council (WRC), this diagram replaced older models like the Schaeffler and DeLong charts to provide unmatched accuracy for modern alloy chemistry. wrc-1992 diagram calculator

formula excludes Manganese because its effect on ferrite formation is non-linear and varies based on the overall composition. Inclusion of Copper (

: In duplex stainless steels, a balanced ratio of austenite and ferrite (often 30–70 FN) is necessary for optimal corrosion resistance and strength. The WRC-1992 Formulas Inclusion of Copper ( : In duplex stainless

Modern readers might scoff. Why not just use a spreadsheet? In 1992, portable computing was a joke. A Toshiba T4400SX laptop weighed 7.5 kg, had a 25MHz processor, and would die after 45 minutes of vibration on a Finnish gravel stage. The weighed 50 grams, never crashed, and worked in a sandstorm. had a 25MHz processor

between inside the FA zone prevents micro-fissuring during solidification.

: Solidifies completely as ferrite. Common in duplex stainless steels, requiring higher FN values (typically 30 to 60 FN) to ensure a balanced 50/50 microstructure. Industry Applications

) : Copper is accounted for with a coefficient of 0.25, improving accuracy for copper-bearing stainless steels.

This process allows for rapid virtual testing, enabling engineers to evaluate how changes in filler metal composition or base metal dilution will affect the final weld's properties.
