Selecting Steels for Case Hardening

Abstract

Case hardening involves various methods and each method has unique characteristics and different considerations in the selection of steels This article reviews the various grades of carburizing steels, carbonitriding steels, nitriding steels, and steels for induction, or flame hardening. This review is based on their process characteristics, compositions, applications, and mechanical properties, which help in selecting steels for case hardening.
