steel stud boxes

Now that I'm done putting up all steel studs in my basement I'm ready to install the outlets. I've read use plastic boxes, use metal boxes, put them on the studs, put them on a 2X4 across the studs. I will be running NM-B 12/2 romex wire with gromets in the studs. I am leaning toward 4x4 steel boxes with mud rings attached directly to the steel studs. Or should I use the plasitic boxes with the issue of the studs needed to be grounded? Either one what is the correct bracketed box? Also i was thinking of installing them at 18".
Thank you, Ed

I would use all metal boxes, with either MC cable or conduit.

Using NM-b is fine as long as you install the plastic bushings. The cable also needs to be secured within 12" of the box and every 4.5', cables through holes in the stud is considered secured/supported.

You can either use a 4" square box that have brackets on them, or use a box bracket such as a B-line BB4-23.

As Tolyn mentioned, the cables must be secured, but cable staples obviously will not work with steel studs. Most common is the use of Colorado Jim supports for either MC cables or NM-B (aka romex) cables.
