METHOD FOR MAKING A MECHANICAL COMPONENT, AND RESULTING MECHANICAL COMPONENT |
| 摘要 |
The invention concerns a method for making a steel mechanical component, characterised in that the steel composition is, in wt. %: 0.12 </= C </= 0.30 %; 0.8 </= Si </= 1.5 %; 1.0 </= Mn </= 1.6 %; 0.4 </= Cr </= 1.6 %; 0 </= Mo </= 0.30 %; 0 </= Ni </= 0.6 %; 0 </= Al </= 0.06 %; 0 </= Cu </= 0.30 %; 0 </= S </= 0.10 %; 0 </= P </= 0.03 %; 0 </= Nb </= 0.050 %; the balance being iron and impurities resulting from the manufacturing process, and it consists in subjecting the component to low-pressure carburizing and low-pressure carbonitriding. The invention also concerns the resulting mechanical component. |
