The is a critical tool in welding metallurgy used to predict the Ferrite Number (FN) and solidification mode of stainless steel weld metals . It is often preferred over the older Schaeffler and DeLong diagrams because it more accurately accounts for the effects of nitrogen and copper on the final microstructure. Calculation Formulas
To use it, the co-driver would rotate the inner disc to align the "crest" marker with the "compression" marker, then read the result through a hairline cursor. A well-trained co-driver could perform a complex five-variable calculation in under 8 seconds while reading pacenotes at 160 km/h. wrc-1992 diagram calculator
Today, the is rarely a physical graph. Instead, marine engineers rely on: WRC-1992 constitution diagram The is a critical tool
system, which is more reliable for measuring magnetic ferrite content. Hot Cracking Prevention: Software & Manual Calculation Tools To use it,
: A small amount of ferrite (typically 3–8 FN) is often required in austenitic stainless steel welds to prevent solidification cracking. Controlling Properties
