Product Description

ASTM 52100 1.3505 100cr6 Suj2 En31 Bearing Steel


1: 52100 steel introduction

AISI/ASTM 52100 bearing steel is a high carbon, chromium containing low alloy steel that is through hardening and noted in particular for use as bearings.
 

52100 bearing steel is one kind of special steel with features of high wear resistance and rolling fatigue strength. High-carbon chromium bearing steel, engineering steel and some types of stainless steel and heat resistant steel are used as materials of bearings and for other purposes.

Advantages of Chrome Bearing Steel 52100:

• Superior hardness, 60-67 on Rockwell hardness scale (Rc) at room temperature
• High carbon chrome alloy steel
• Operates continually at temperatures up to 120°C
• Used to produce precision ball bearings and roller bearings
• Cost-effective
• Long working life
