Features:
1) Grade: Bearing steel SAE52100 / GCr15 round bars
2) Diameter: 50-500mm
3) Delivery condition: EAF LF VD, hot rolled/forged,spheroidized

annealed, black/peeled/machined, UT tested 

4) Commom steel used to produce balls and rings of bearing. Theproduct has characteristics of uniform-chemical composition, lowpercentage of harmful elements, high purity, well-distributedcarbide, good surface quality. It also has characteristics of widescope of plastic,stable heat-treatment quality, uniformand highhardness, high wear resistance,high strength of touching fatigue.It has excellent machining property afer spheroidize annealing.
The use of products The product is used to produce balls and ringsof bearing. Future Development By rational rolling and coolingprocess, the product can be spheroidized on-line and can be used indrawing and machining directly by customers. By combiningre-spheroidize annealing and re-crystallisation of semi-finishedproduct, the steel wire process can be simplified.
