Abstract

Disclosed herein is an improved method of finishing a steel article having a carburized and boronized case. The article is carburized to a selected depth then finished to a smoothness which is smoother than the desired final finish. The article is then boronized, hardened and tempered. Further finishing is unnecessary.
