4) Commom steel used to produce balls and rings of bearing. The product has characteristics of uniform-chemical composition, low percentage of harmful elements, high purity, well-distributed carbide, good surface quality. It also has characteristics of wide scope of plastic, stable heat-treatment quality, uniformand high hardness, 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 rings of bearing. Future Development By rational rolling and cooling process, the product can be spheroidized on-line and can be used in drawing and machining directly by customers. By combining re-spheroidize annealing and re-crystallisation of semi-finished product, the steel wire process can be simplified.
