Pre-cooling isothermal quenching method
Pre-cooling isothermal quenching method
Pre-cooling isothermal quenching method: also known as heating isothermal quenching, the parts are first cooled in a bath with a lower temperature (greater than Ms), and then transferred to a bath with a higher temperature to make the austenite undergo isothermal transformation. It is suitable for steel parts with poor hardenability or large workpieces that must be austempered.
