ALLOY & CARBON STEEL EN24

EN24 is an extremely famous grade of through-hardening alloy steel, which is promptly machinable in the "T" condition. (Allude to our machinability guide).


EN24T is most suitable for the assembling of parts, for example, heavy-duty axles and shafts, gears, bolts and studs. EN24T can be further surface-solidified normally to 58-60 HRC by induction or nitride forms, delivering parts with upgraded wear resistance.


It is therefore suggested that bigger sizes are supplied in the annealed (softened) condition, and that quenching and treating is done after introductory stock removal. This ought to accomplish better mechanical properties towards the core.
