BAIN MATERIAL BAIN MAKING METHOD OF BAIN

摘要

Vane material, vane and method of producing a vane to be used in a compressor using a substitute freon, improving the wear resistance thereof. The vane material has a composition consisting of by weight: 1.0-2.5% of C; not more than 1.5% of Si; not more than 1.0% of Mn; 3-6% of Cr; one or two of not more than 20% W and not more than 12% Mo where "W+2Mo" being 15-28%; 3.5-10% of one or two of V and Nb; and the balance of Fe and incidental impurities. Carbides are uniformly dispersed in the matrix thereof where their average diameter does not exceed 1.5 mu m and the maximum diameter thereof does not exceed 6 mu m. A method of producing a vane is also disclosed, in which an atomized powder having the composition as described is compacted and it is then subjected to hot working, or to hot working and cold working.
