A process for hardening steel surfaces by induction heating followed by quenching.
- ‘In induction hardening, this is accomplished by the close regulation of power output, operating frequency, heating time, and alloy content of the iron.’
- ‘In flame and induction hardening, a large content of combined carbon is required because of the short period available for the solution of carbon in austenite.’
- ‘In comparison with a structural steel hardened in a furnace cheaper carbon steel can be used with higher strength after induction hardening.’
