  The antiferromagnetic ordering of chromium has long been known for its
peculiar physical properties. One of them is the observation of the weak
first-order character of the N'eel transition that is explained by the lack of
a stable fixed point by Bak and Mukamel. Barak et al. predicted that by
lowering the symmetry of the order parameter by the application of uniaxial
pressure along the [110] direction changes the N'eel transition to
second-order. In a previous experiment by Fawcett et al., irreversible
broadening of the N\'eel transition was already observed between 160 bar and
300 bar, which could, however, be caused by plastic deformation. Using an
improved setup with reduced stress inhomogeneities we succeeded to increase the
pressure range until irreversible broadening is observed above 450 bar. Despite
the observed tripling of the intensity of the magnetic Bragg peak $[0, 0,
1-\delta]$ at $p_{[110]}\geq450\,$bar, indicating a single
$\bf{\text{Q}}_\pm$-domain state of the sample, no hints for a tricritical
point were observed.
