NI-RESIST TYPE D5S -- AN IMPROVED MATERIAL FOR TURBOCHARGER HOUSINGS

Automotive turbocharger housings are complex castings of predominantly thin section requiring a demanding combination of properties. Ni-resist Type D5S, a highly castable austenitic ductile iron provides the required combination of properties and is finding increased application in turbocharger housing. A series of investigations has been conducted into the influence of melting/casting and compositional variables on microstructure, mechanical and physical properties, and machinability of this iron. A preferred melting/casting practice is recommended, and the effects of various addition elements are defined.
