製品の説明

GCr15 / SAE52100 / EN31 Alloy Steel Round Bar for Bearing

Product Overview

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 excellent performance and minimal alloy content
High hardenability and comprehensive mechanical properties
Excellent machinability after spheroidizing annealing
High hardness, uniform structure, superior wear resistance, and high contact fatigue performance after heat treatment
Outstanding hot working performance
