WebCritical temperature of steel defines phase transition between two phases of steel. As the steel is heated above the critical temperature, about 1335°F (724°C), it undergoes a phase change, recrystallizing as austenite. There are two types of critical temperature: Lower critical temperature (Ac1). Web(Bottom) The iron / carbon phase diagram, which shows temperatures at which phase change occurs. Heat treating works by exposing carbon steels to a range of specific temperatures for a prescribed period. ...
