Wrc-1992 Diagram Calculator Extra Quality -

The 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

The diagram was developed by D.J. Kotecki and T.A. Siewert to specifically address issues with nitrogen-containing steels and to provide a more accurate prediction of Ferrite Number (FN) rather than volume percent ferrite, which was common in older methods.

This calculator helps you:

In the world of stainless steel welding, "guessing" isn't an option. Whether you are working with standard austenitic grades like 304 or high-performance duplex steels, the balance of your microstructure determines if your weld will stand the test of time or crack under pressure.

This is the traditional method. An engineer would take the chemical composition of a weld, manually calculate the Cr and Ni equivalents using the formulas, and then plot the point on a printed WRC-1992 chart. The manual method is a valuable learning exercise but is time-consuming for everyday use in a fabrication shop.

Despite the rise of 3D FEA, the remains a cornerstone of marine engineering education and preliminary design. Its enduring value lies in three facts:

Austenitic stainless steels are prone to cracking during solidification if they are fully austenitic. A small amount of delta ferrite (typically 3–10 FN) acts as a "solute trap," absorbing impurities and preventing the formation of continuous liquid films that lead to cracks. The calculator confirms if the composition falls within the safe "A+F" (Austenite + Ferrite) zone.
