1.2842 90 MnCrV 8

Cold working tool steel for the manufacture of tools, gauges, jigs, templates, guideways and components of all kinds.

This material is obtained from us as a raw material, round and flat, as a precision flat steel, as VarioPlan with fine machined thickness, as VarioRond as well as individually to your specifications as standard material for machine components and hardened guideways under 40mm thick.

When heat treating, it must be borne in mind that 1.2842 is a through-hardener which undergoes a volume change during heat treatment of approx. 1 ‰ yet exhibits very low-distortion behaviour. Work piece cross-sections over 40 mm thick can result in partial lower hardnesses than 58 - 62 HRc. For larger guideway component cross sections we recommend 1.2363 or the cementing in of hardened ways, for machine parts even 1.2379.

It machines well and is not problematic.
