WRC 1992 Constitution diagram with SA 240 type 316L Cr and Ni equivalence range indicated. +2 WRC 1992 Constitution diagram with SFA-5.9 A Martensite Boundary on the WRC-1992 DiagramThe WRC-1992 diagram (Ref. 1) for stainless steel weld metals has been rec- ognized by the International Institute of Welding (IIW) as the most accurate and preferred constitution diagram for esti- mating or predicting ferrite in nominally austenitic and duplex ferritic-austenitic stainless steel weld metals (Ref. 2).
The diagram consists of the Ni-equivalence on the vertical Y-axis and of the Cr-equivalence on the horizontal X-axis. There are several nearly parallel straight lines corresponding to constant ferrite numbers (FN i.e. approx. ferrite content).

A rapid way of estimating ferrite content and thus microstructure is by using weld metal composition and a Welding Research Council (WRC)-1992 diagram. The ferrite-forming alloying elements are estimated to a chromium equivalent, the austenitic to a nickel equivalent and the ferrite content is estimated by help of isoferrite lines.

@Dinesh Rathod sir the cr and nickel equivalent of the weld is 10.5 and 0.66 respectively, how to put this in WRC-1992 diagram. sir can you please suggest me any article for better understanding Schaeffler Diagram - an overview ScienceDirect TopicsThe WRC diagram provides reasonable agreement in many practical applications, 17 although for relatively low and high nitrogen contents (<0.19%N and >0.26%N), FN values are over- and under-estimated respectively. 37 This may imply that a variable factor for nitrogen is required, as proposed by DeLong in 1956 38 or that cooling rate should be considered. 39 Nevertheless,

nite-forming elements (C, Ni, Mn, Cu, N). The position in the Schaeffler diagram defined by the Cr- and Ni-equivalents gives the proportions of martensite, austenite and ferrite in the resulting microstructure. Other constitution diagrams (e.g. Delong, WRC ferrite calculations - Metal and Metallurgy engineering Jan 31, 2004 · I use Schaeffler-DeLong diagram and corresponding formulas. It takes the most elements into consideration. A very simple spreadsheet can do all the calcs if you just input the element percentages, that is if you run ferrite calculations a lot.
WRC-1992 diagram solves many of the problems faced with the Schaeffler and DeLong diagrams. WRC Diagram was developed with data measured by the most recent definition of the Ferrite Numbers (FN) scale, it removed the erroneous Mn coefficient from the Ni eq and eliminated the systematic overestimation of FN for highly alloyed weld metals.
