摘要： The invention relates to a ball pin made of a steel comprising a bainitic microstructure having the following composition in weight percent: iron, and - 0.05 to 0.15 carbon - 0.10 to 0.4 silicon - 1.0 to 2.5 manganese - 0.0015 (15 ppm) to 0.0120 (120 ppm) boron, in total 0.06 to 0.30 of the elements vanadium, niobium, titanium. A method for producing the ball pin comprises at least the following steps: melting the steel; casting the steel in ingot casting or continuous casting; hot rolling; controlled cooling after the hot rolling; cold drawing; extrusion.

摘要： The invention relates to a manufactured steel chain blank comprising, in weight percent, between 0.17 and 0.26 % carbon, between 0.9 and 1.5 % manganese, up to 0.02 % phosphorus, up to 0.02 % sulphur, between 0.9 and 1.5 % nickel, between 0.3 and 1.0 % chromium, up to 0.25 % copper, between 0.4 and 1.0 % molybdenum, between 0.02 and 0.05 % aluminium, between 0.02 and 0.06 % titanium and up to 0.012 % nitrogen, in addition to admixtures that are usually used in the production of steel. The silicon content lies between 1.0 and 1.6 wt %.
