The effects of austenitizing, cold rolling and aging conditions on the mechanical properties, corrosion resistivity and microstructure of 17-7 PH stainless steel containing 1.15%Al or 1.54%Al were investigated. The results obtained are summarized as follows: (1) When the austenitizing temperature was in the range of 750°∼825°C, no remarkable difference was observed in the mechanical properties of this steel after aging.<BR>(2) As for the steels containing 0.73∼1.54%Al, a rapid increase in hardness took place in the early stage of aging, following which a slow hardening continued to the maximum hardness. While the increase in the Al content which promoted the hardness augmentation in the early stage delayed the peak hardness to be reached.<BR>(3) An experimental formula for the relation between the Al content and the aging time required to obtain the best mechanical properties at each aging temperature is as follows: t = 5.144×(Al%)^1.476×10^10438/T-14<BR>(4) In 40 wt% nitric acid solution (boiling), all the specimens attained a passive state and showed excellent corrosion resistance.<BR>(5) In 10 wt% sulfuric acid solution (30°C), specimens which were aged at 400°∼500°C after austenitizing treatment for the duration in sufficient to get the maximum hardness or aged after cold rolling, attained a passive state and showed good corrosion resistance.
