Cr-Mo P/M Steels as a Cost Effective Replacement for Traditional Ni-Mo P/M Steels

Recent advances in powder manufacturing and processing have made chromium an attractive element in P/M manufacturing. In addition to chromium’s positive affects on strength and hardenability, it is also a cost effective alternative to traditional alloying elements, such as nickel and molybdenum. The purpose of this paper will be to demonstrate how a Cr-Mo alloy, Astaloy CrL, can be used to replace a more expensive, traditional alloy system,FLN2-4405. Sintered and heat treated properties will be presented.
