We present the deepest Chandra High Energy Transmission Grating Spectrometer observation of the Seyfert 1 galaxy MCG --6-30-15 to date. Concentrating on the hard X-ray band we note the continued presence of the relativistically broadened iron K\alpha fluorescence line, and discuss the various narrow emission and absorption features in this band. In particular, we find narrow, weak H- and He-like iron absorption lines, but no evidence of K-shell absorption lines from less highly ionized iron, supporting the relativistic disk line interpretation of the broad iron line. This work is supported by NASA contract NAS8-01129.
