Abstract
A process for production of a steel component having a hard, carbon rich dissolved surface and a tough, low carbon dissolved core, incorporating the following steps: PA1 using an alloyed steel with a carbon content of 0.3%-1.2% C and with an alloy element acting as a strong carbide former; and PA1 subjecting a component formed from this material to induction heating, whereby the core is heated to a level in the lower region of the austenite area, thereby creating a certain dissolved low carbon level in the component core, and rapidly heating the surface region to a higher region within the austenite area, thereby creating a high dissolved carbon content in the surface region of the component.
