Product Description
GCr15 / SAE52100 / EN31 Alloy Bearing Steel Forged Round Bars
High carbon chromium bearing steel round bars specifically designed for forming tools, hand taps, and bearing applications.
Product Introduction
GCr15 is a high carbon chromium bearing steel with optimized alloy content. After quenching and low temperature tempering, it delivers high hardness, uniform microstructure, excellent wear resistance, and superior contact fatigue performance.
Key Features
- Widely used high carbon chromium bearing steel with optimal performance and minimal alloy content
- Excellent hardenability and comprehensive mechanical properties
- Superior machinability following spheroidizing annealing
- High hardness, uniform structure, exceptional wear resistance, and high contact fatigue performance after heat treatment
- Outstanding hot working performance
