Abstract
PURPOSE: To produce a hardened piston ring made of seel of superior dimensional and shape accuracy by heating a strip-like steel material to a high temperature, forming the same into a ring shape within the specific temperature range while quenching the same then causing its martensite transformation in that state.
CONSTITUTION: A strip-like steel material for piston rings is heated to above its austenite transformation point. This is quenched and is kept in an austenite state without causing Ar1 transformation. It is then formed into a ring in a 600W750°C temperature region. The ring is quenched while being held restrained by forming jigs to cause martensite transformation at an Ms point without producing any ferrite. It is hardened in that shape, after which it is tempered, whereby the hardened ring made of steel of a stable shape may be produced by the simple process.
