Applications
EN24 was originally introduced for use in the motor vehicle and machine tool industries for gears, pinions, shafts, spindles and the like. Later its applications became much more extended. Suitable to produce parts for such as locomotives, cranes, rolling mills, coal cutting machinery etc. where good strength and fatigue resistance is called for. Other applications for EN24 and EN24QT are found in die casting and hot metal working, such as die bolsters, racks and pinions, angle pins for pressure die casting, hot stamping dies for aluminium stamping, die beds for steel stamping, lower temperature nut, bolt and rivet heading dies, large section drop forging dies. It is widely used in the plastic and rubber molding industries for molds (particularly rubber molds), hob retaining rings, patens, retaining rings for built up molds, stop pins for molds. For molds EN24 is normally supplies hardened and tempered to ‘T’ condition. If a higher hardness is desired EN24T should be annealed and then heat treated to the required hardness.
