The excellent alloy material, mechanical processing means and heat-treatment technology, make the Titanium alloy steel ring more smooth surface, accurate in size, less distortion, and more compact fine texture.

It endows strong resistant performance, its life can be twice than that of normal steel 20#, nearly reach to the resistant performance of bearing steel.

It can obviously promote the yarn quality, can decrease the filoplume, depress end breakage, and heighten quality of yarn and spinning efficiency.

It can meet the requirement for high-speed yarn more rational, conforms to the situation in china, can deduce the cost of spinning mills.
