Forged High Wear Resistance Bearing Steel Round Bar GCR15 / 52100 / SUJ2
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:
1. Supply Range of ASTM 52100 Bearing Steel
AISI 52100 Steel Round Bar: diameter 8mm – 800mm
52100 Steel Plate: thickness 2mm –300mm x width 200mm – 800mm
Other sizes of 52100 steel as per customer’s requirements
Process: Cold drawn, hot rolled, forged etc.
Surface Finish: black, rough machined, turned, polished or as per given requirements.
