Applications of 31CrMoV9 round bar, hot-rolled, quenched, tempered and stress-relieved
31CrMoV9 steel (1.8519), also listed in some catalogues as 31CrMoV10, in hot-rolled round bars, quenched, tempered and stress-relieved, represents an excellent solution for components requiring high wear resistance. The presence of vanadium, combined with chromium and molybdenum, ensures superior mechanical properties.
This material is particularly suitable for manufacturing components subject to severe operating conditions such as plastic moulds, gears and mechanical parts subject to heavy wear. Stress relieving ensures maximum dimensional accuracy during nitriding.
The structure obtained after quenching, tempering and stress relieving ensures an excellent combination of surface hardness and core toughness, key characteristics for critical mechanical applications.
