We report our analysis of X-ray spectra of the Seyfert galaxy IRAS 18325–5926 ( =Fairall 49 ) obtained from various X-ray observatories prior to XMM-Newton , including new results from two RXTE and one BeppoSAX observations .
A relatively steep continuum slope ( \Gamma \simeq 2.2 ) in the 2–15 keV band is confirmed .
The continuum spectrum observed with the BeppoSAX PDS shows a possible roll-over at energies above 30 keV , indicating a Comptonizing corona cooler than in other Seyfert nuclei .
The X-ray spectrum above 2 keV is best explained with a model including reflection from a highly ionized disk with significant relativistic blurring .
The iron K \alpha emission feature is then mainly due to FeXXV .
The recent seven observations shows that the iron K emission flux appears to follow the continuum between the observations separated by a few months to years , although some exceptions suggest that the line strength may be determined in a more complex way .
