ABSTRACT:
An improved vane for a rotary fluid compressor for which the rate of abrasive wear is matched to that of the mating rotor. The vane is made from a steel material consisting of 0.7-1.3 wt % of C, 13-20 wt % of Cr, and at least one of 0.3-1.5 wt % of Mo and 0.07-0.15 wt % of V, the balance being iron. Alternatively, the material may further contain not more than 1.0 wt % of Si and not more than 1.0 wt % of Mn. A vane so formed is ideal, in abrasion characteristics, for use with a Mo-Ni-Cr cast iron rotor.
