摘要： The invention relates to a bainitically hardened brake disk comprising at least one ring-shaped cast disk (1) body with radially extending ring sections in contact with brake shoes (2). Said brake disk is mounted on the hub of a bicycle wheel (5) for braking purposes. In order to avoid noise emissions and vibrations, the inventive disk is made of cast iron, is highly tough and has a low weight. The aim is to avoid the disadvantages of combining disk brakes with an aluminium wheel hub. The inventive disk is characterised in that it has a thoroughly bainitically hardened body (1) made of cast iron with lamellar graphite (AGI), the brake disk is designed as a single piece and is linked to the wheel hub (5) through composite casting by forming a positive material fitting joint (15) in the area where the hub (5) is connected to the base (3) of the disk.

摘要： A seal ring (100) comprising a chromium and boron containing cast iron alloy composition is disclosed. The cast iron alloy composition comprises each of boron, chromium and silicon in the following amounts: boron up to 1.5 wt. %; chromium from 8 to 14 wt. %; and silicon up to 3.0 wt. %. The seal ring (100) may be produced by melting a cast iron composition further comprising the foregoing alloying elements; pouring the melted alloy into a mold; cooling the melted alloy to form a cast iron seal ring; and separating the cast iron seal ring from the mold. The seal ring is typically used in the undercarriage of earth-working machines, such as in the drive train or power train of such machines.

The invention further comprises a method of preparing a malleable iron having a high nodule count comprising the steps of prenucleating a malleable iron casting at a temperature of about 600 to 900 DEG F for about 3 to 6 hours; austenitizing the prenucleated casting at about 1680 to 1740 DEG F for about 3 to 9 hours to form graphite nodules such that the malleable iron has about 250 to 400 nodules per mm ; and quenching the casting to form pearlite and a malleable iron made by this process.
