Heat Treatment of Steel Paşa Yaman FVTM, UJEP Ústi nad Labem, ČR Heat Treatment of Steel • Steels can be heat treated to produce a great variety of microstructures and properties. The steel heat treatment process consists of heating the steel fasteners into the Austenite range, that is to a high temperature 840℃~980℃ (1,550℉~1,800℉), in which the steel becomes "red hot" for some time. Contact: +46 293 306 00 , sales@damasteel.se By heat treating, a metal can be made harder, stronger, and more resistant to impact, heat treatment can also make a metal softer and more ductile.
