The simplest heat-treating process is normalizing. This consists of holding steel for a short time at a temperature 20° to 40° C above the G-S-K line (shown in the iron-carbon diagram in the figure) and then cooling it afterward in still air. Holding the steel in the gamma zone transforms the as-rolled or as-cast microstructure into austenite
