Solidifies as primary ferrite, transforming partly to austenite during cooling. This is the ideal zone for most austenitic welding, yielding a safe range of 3 to 10 FN to prevent hot cracking. F Field (Ferritic): Solidifies completely as ferrite. Why Use a WRC-1992 Diagram Calculator?

If you find a genuine 1992 Martini Racing Lancia unit, expect to pay €800–€1,500. These were never sold commercially; they were team-issued and often destroyed after the season.

Understanding the WRC-1992 Diagram: The Ultimate Calculator Guide for Stainless Steel Weldments
To understand the calculator, you must understand its three component "diagrams." Why Use a WRC-1992 Diagram Calculator
When welding stainless steel to carbon steel (e.g., using a 309 filler metal), the composition is diluted. A calculator is essential here to ensure the "diluted" chemistry still falls within the safe zone, preventing martensite formation or cracking.
While powerful, the WRC-1992 diagram is not a substitute for physical testing.
The calculator emulates the – nomographs relating field strength, distance, frequency, and time percentage. The main steps: These were never sold commercially; they were team-issued
This represents the combined effect of elements that stabilize (the non-magnetic phase). Formula:
By plotting the points on the WRC-1992 diagram, the point representing the weld metal (C) falls between the FN=40 and FN=46 iso-ferrite lines. This allows a skilled interpreter to predict the FN of the weld metal to be approximately 42.7 .
In a modern engineering setting, a (often an Excel tool or online widget) serves as the "oracle" before a single arc is struck. A user enters the chemical composition of their base metal and filler rod, and the calculator solves for two critical values: Chromium Equivalent ( Creqcap C r sub e q end-sub
