Carburized steel-update on a mature composite

  • Douglas V. Doane
Article

Abstract

This review of properties and applications of carburized steel provides an historical perspective from which to examine current efforts to improve this important ferrous composite. The carbon-rich case, useful for its wear resistance, also interacts with the low carbon core during quenching to generate favorable residual stresses which enhance the load carrying ability of the composite. The paper will review the control of core and case microstructure, the importance of case hardenability, and the influence of surface oxidation. Fatigue behavior, with and without superimposed overloads, will be summarized, and a relationship between overload fatigue and impact fracture will be reviewed. The review presents good evidence that the performance of carburized steel can be optimized by alloying, and that alloy selection can have a significant effect on engineering properties. Metallurgical data can aid the processing of carburizing steel; available data, and their effect on machinability and distortion control, are reviewed.
