Iron base sintered alloy for structural member of fuel supply apparatus

Abstract

Abstract PURPOSE:To obtain a sintered alloy for the structural member of a fuel supply apparatus having anti-wear property, compatibility and corrosion resistance even if used in supplying low grade gasoline or alcohol containing gaseoline, by containing a specific amount of C, Cr and one or more of P, B, Si in steel. CONSTITUTION:The structural member of a fuel supply apparatus has a composition consisting of, on the wt% basis, 0.5-3.5C, 5-35 Cr, one or more of 0.03-3 P, B or Si and the remainder of Fe and inevitable impurities. By employing this composition, carbide is fundamentally dispersed and precipitated throughout a Fe base alloy material as well as a structure wherein Cr is dissolved in the material to form a solid solution is obtained and, therefore, anti- wear property, compatibility and corrosion resistance are enhanced. In addition, other than aforesaid components, one or more of 0.5-10 Mo, W, one or more of 15-10 Ni, Co, Cu, one or more of 0.05-10 Nb, Ta, Ti, Zn are pref. contained.
