·全新材料；采用優(yōu)質(zhì)軸承鋼鋼材制造，比普通20鋼內(nèi)部組織結(jié)構(gòu)緊密、均勻，熱處理變形量小，材質(zhì)性能穩(wěn)定。

· 優(yōu)良的使用性能，表面采用高科技手段，鍍有自潤(rùn)滑耐磨層，降低了鋼令與鋼絲圈之間的摩擦系數(shù)，上車走熟期極短

· 表面經(jīng)特殊工藝拋光后鍛造度極低。紡紗性能極為穩(wěn)定。斷頭少，毛羽少，紡紗質(zhì)量穩(wěn)定期較長(zhǎng)。

·在確保紗線質(zhì)量穩(wěn)定的前提下，使用壽命為原來(lái)傳統(tǒng)光面鋼領(lǐng)壽命的2-3倍。

New material:The ring is made of high quality bearing steel.Compared with the common No.20 steel, its internal structur is compact and uniform, featuring in little deflection og heat treatment and stable material performance.
Excellent persormance;Self-lubrication wearable material coated on the surface og the ring by higg-tech process reduces the friction paameter betwen the ring and the ring traveler,which allows short period to smooth running.
Low roughness resulting from special surface polishing process alows stable spinning,low end breakage and low hairiness.
On the permise of the stable good quality, the service life of the ring is 2 to 3 times than that of the traditional one.
