Austempering comprises raising the temperature of a steel until its structural condition is completely austenitic, i.e. well above its upper critical point,and then immersing it in a molten lead or salt bath heated to and rigorously maintained at a chosen temperature, which cools it quickly to this temperature,but is above the temperature at which the austenite in the steel normally changes to hard martensite when quenched in oil or water at ordinary temperature.
