Abstract

1441091 Carbonitriding iron alloy piston-rods BARKAS-WERKE VEB 7 Aug 1973 [15 Aug 1972] 38031/72 Heading C7U [Also in Division F2] Iron alloy piston-rods are carbonitrided in a solid, liquid or gaseous medium to produce a surface layer consisting of nitrides and carbonitrides of the base iron material and its alloy elements, with a thickness of at least 4Á.
