Method for production of a sintered component

2:

• The method according to claim 1, wherein at least one gas from a group consisting of oxygen, carbon dioxide, hydrogen is contained in the decarburizing atmosphere, wherein the proportion of the gas amounts to between 0.1 vol.-% and 10 vol.-% of the atmosphere.

3:

• The method according to claim 1, wherein the C proportion in the sintering green compact is reduced by maximally 0.6 wt.-%.

4:

• The method according to claim 1, wherein after surface-compacting in the last matrix section (11) having a decreasing inside diameter (17), relaxing of the sintered component (2) is carried out in a stress-relief section (21) that directly follows the last matrix section (11), which stress-relief section (21) has a greater inside diameter (22) in comparison with the last matrix section (11) configured directly ahead of it of the matrix section (7-11) having a decreasing inside diameter (17), wherein the sintered component (2) is calibrated in the stress-relief section (21), for which purpose the inner contour of this stress-relief section (21) corresponds to the reference contour having a reference dimension of the sintered component (2).

5:

• The method according to claim 1, wherein the chromium proportion of the powder amounts to between 0.1 wt.-% and 10 wt.-%.

6:

• The method according to claim 1, wherein hardening takes place by means of carburizing and subsequent quenching or sinter-hardening and subsequent quenching or inductive hardening.

7:

• The method according to claim 6, wherein carburizing is carried out by means of low-pressure carburizing.

8:

• The method according to claim 6, wherein quenching is carried out using a gas.
