Product Details

ASTM A 485 is a specification for high hardenability antifriction bearing steel. It’s used in a variety of mechanical applications due to its good versatility. Processing performance, hardness and abrasion resistance can be developed by heat treatment to make the steel particularly suitable for applications where requiring extreme wear resistance like bearing application. The commonly used grades are ASTM A 485 Gr1 and Gr3.

 

The Equivalent Standards: JIS G4805 SUJ3, SUJ5

Out diameter: 1.0-200mm
