31CrMoV9 / 1.8519 / ~15330 – Nitriding steel
31CrMoV9 / 1.8519 / ~15330 is CrMoV alloyed nitriding steel used mainly in automotive industry and in mechanical components in general, due to its high wear resistance. Properties: high wear resistance, high pressure resistance, heat treatable, highly hardenable on the surface, difficult to weld. For this reason, it should not be used in welded constructions.
31CrMoV9 / 1.8519 / ~15330 material is directly comparable with the 30CrMoV9 / 1.7707 / 823M30 / ~15330 hardly hardenable, nitriding steel (after nitriding, the surface hardness of up to 800 HV can be achieved) and it is its possible equivalent.
