BAINITIC STEELS FOR PASSENGER CAR AND LIGHT COMMERCIAL VEHICLE BALL PINS |
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. |
