Development of css-42l~(tm~5), a high performance carburizing stainless steel for high temperature aerospace applications

摘要

Today's aerospace engineeirng challenges demand materials which can operate under conditions of temperature extremes, high loads and harsh, corrosive environments. This paper presents a technical overview of the on-going development of CSS-42L~(TM) (US Patent 5, 424, 028)~((1)). This alloy is a case - carburizable, stainless steel alloy suitable for use in applications up to 427 deg C (800 deg F), particularly suited to high performance rolling element bearings, gears, shafts and fast eners.
