Analysis of High Carbon Chromium Bearing Steel

Introduction

High carbon steel and steel alloys used for mechanical parts and construction are called specialty steel and are utilized widely in various fields including automobile and aircraft industries. Specialty steel is subjected to a heat treatment, which is called quenching and tempering, to refine the mechanical properties such as strength and toughness. In the case of bearing steels or tool steels that contains a high percentage of carbon, annealing is performed to obtain an intended property. Carbon steel that contains over 0.6 % carbon (C) is classified as high carbon steel, among which bearing steel is a typical steel type. This article introduces an example analysis of high carbon chromium bearing steel (SUJ) using a field emission type electron probe microanalyzer (Shimadzu EPMA-8050G).
