Abstract

1441092 Gas nitriding BARKAS-WERKE VEB 30 Aug 1973 [6 Sept 1972] 41242/72 Heading C7U [Also in Division F2] Metal articles, e.g. steel piston-rods, nozzles or punches, are gas nitrided by heating in a gas mixture consisting of ammonia, carbon monoxide and optionally argon and/or nitrogen, e.g. in a shaft furnace.
