WRC-107 (1992 revision) covers six fundamental load types:

were the go-to tools. However, modern stainless steels often include specific alloying elements that these older models didn't fully account for. The WRC-1992 diagram introduced several critical improvements Nitrogen (N) and Copper (Cu) Inclusion:

WRC-1992 diagram (Welding Research Council) is a standard constitution diagram used to predict the Ferrite Number (FN) and the final solidification mode of stainless steel weld metals. It is widely considered the most accurate manual method for copper-bearing stainless steels and duplex stainless steel welds. Welding Knowledge

The WRC-1992 diagram is a fundamental tool used by welding engineers, metallurgists, and fabricators to predict the microstructure of stainless steel weld metals. Developed by the Welding Research Council (WRC), this diagram determines the balance between ferrite and austenite in a weld. This balance is critical because it directly impacts a weld’s resistance to cracking, corrosion, and mechanical failure. What is the WRC-1992 Diagram? : Obtain the exact chemical composition of your

The WRC-1992 diagram introduced several improvements over older metallurgical diagrams: : The Nieqcap N i sub e q end-sub

: Primary ferrite solidification with secondary austenite. This is the ideal zone for standard austenitic stainless steels (like 304 and 316) to prevent hot cracking, typically requiring a Ferrite Number between 3 and 10 FN. Welding Knowledge The WRC-1992 diagram is a fundamental

Note: The WRC-1992 version specifically added the coefficient (0.25) to improve accuracy for copper-bearing and duplex stainless steels. How to Use the WRC-1992 Diagram as a Calculator

In COC oral exams and marine engineering textbooks, when someone refers to "the WRC-1992 diagram calculator," they mean the to input geometric parameters and output stress indices.

). These values represent the stabilizing effect of various alloying elements on the ferrite and austenite phases, respectively. The formulas used in the WRC-1992 diagram are:

Maintaining a specific FN (typically 3–8 FN for austenitic steels) is critical to preventing solidification cracking.
