Steel - Effects of heat-treating Britannica

Steel - Steel - Effects of heat-treating Adjusting the carbon content is the simplest way to change the mechanical properties of steel.Additional changes are made possible by heat-treating—for instance,by accelerating the rate of cooling through the austenite-to-ferrite transformation point,shown by the P-S-K line in the figure.(This transformation is also called the Ar1 transformation sp.infoSteel - Treating of steel BritannicaSteel - Steel - Treating of steel In principle,heat-treating already takes place when steel is hot-rolled at a particular temperature and cooled afterward at a certain rate,but there are also many heat-treating process facilities specifically designed to produce particular microstructures and properties.The simplest heat-treating process is normalizing.
