PURPOSE:To obtain a ring for a spinning machine contg. uniformly and finely distributed carbides and having superior wear and heat resistances and a long life by using an alloy steel having a specified composition consisting of C, Si, Mn, Cr, Mo, V and Fe. CONSTITUTION:An alloy steel consisting of 0.6-1.2%, preferably 0.8-0.95% C, <=1.0% Si, <=1.0% Mn, 6.0-20.0%, preferably 17.0-19.0% Cr, 0.5-2.0%, preferably 1.0-1.3% Mo, 0.05-0.6%, preferably 0.07-0.17% V and the balance Fe with impurities is worked to a prescribed shape to obtain the ring for a spinning machine having superior toughness, wear and heat resistances and the long life. The early wear of the ring even under severe operational conditions can be prevented. The ring stabilizes the traveling of a traveler and can inhibit the breaking and napping of yarn. |
