Hot Rolled Alloy Steel Seamless Bearing Tube & Pipe
AISI52100/EN31/JIS SUJ2/GBCR15
Product Introduction
Alloy Steel 52100, as known as AISI 52100, contains a high level of
carbon and chromium. This alloy offers users good machinability, as
well as forming through conventional methods. The hardening of
Alloy Steel 52100 can be achieved by cold working, heating, and
quenching.
Features
1. 1 A kind of high carbon and chromium bearing steel which most
widely used with a good permance and less alloy content.
2. 2. High hardenability and good comprehensive performance.
3. 3. Good machinability after spheroidizing annealing
4. 4. High hardness, uniform organization, good wear resistance,
high contact fatigue performance after quenching and tempering.
5. 5. Good hot working performance
