MATERIAL CHARACTERISTICS OF RAILWAY BRAKE DISCS OF VARIOUS IRON-CARBON ALLOYS

The results are described of tests and investigations carried out in the Research Station of the Bergische Steel Industry in Remscheid, on various iron-carbon and steel alloy materials for use in disc brakes on railway vehicles. While chrome-molybdenum steel alloy castings showed some desirable characteristics under repeated heatings, the pearlitic cast iron with lamellar graphitic inclusions showed greater resistance to fine hair line cracking. The group of malleable, ductile and pearlitic cast irons appeared to develop relatively few cracks, up to 6 mm depth and widely dispersed, while the cast steels with no or little alloys sustained many short cracks only 1.2 mm deep. There remains the need for further research for combinations of materials that will withstand better the high and repeated high temperature shocks to which brake discs are subjected.
