Product Description
GCr15 Bearing Steel Round Bar
High-quality SAE52100/100Cr6/GCr15 alloy steel round bars, flat bars, and engineering steels for demanding industrial applications.
Product Overview
GCr15 is a high carbon chromium bearing steel with excellent performance characteristics. After quenching and low temperature tempering, it delivers high hardness, uniform structure, superior wear resistance, and outstanding contact fatigue performance.
Key Features
  • Widely used high carbon chromium bearing steel with excellent performance and minimal alloy content
  • High hardenability and comprehensive performance characteristics
  • Excellent machinability after spheroidizing annealing
  • High hardness, uniform microstructure, superior wear resistance, and high contact fatigue performance after heat treatment
  • Superior hot working performance
