Document Type and Number:
WIPO Patent Application WO/2015/053118
Kind Code:
A1
Abstract:
A heating step of heating a stainless member to a temperature that is equal to or higher than a phase transformation temperature range upon heating (Ar) in which the stainless member can cause phase transformation and a cooling step of cooling the stainless member that has been heated in the heating step to a temperature that is lower than a phase transformation temperature range upon cooling (Mr) in which the stainless member can cause phase transformation are carried out. In the cooling step, the stainless member is prevented from being cooled in a control temperature range including the phase transformation temperature range upon cooling (Mr).
