Cold working steel for the manufacture of cutting tools, thread rolling dies as well as shearing blades and hardened large-section guideways.

The material 1.2363 fills a gap between 1.2842 and 1.2379. Machining is unproblematic, similarly to 1.2842.. The grinding of hardened components is also simple compared with 1.2379. However 1.2363 hardens well under vacuum similarly to 1.2379. In addition, 1.2363 is significantly cheaper than 1.2379 and should be used where 1.2842 is inadequate for the application requirement due to wear resistance or through hardening capability but the 1.2379 is not absolutely necessary. In the case of recurring applications it makes sense to carry out material comparison tests.

This material is obtained from us as precision flat steel, raw flat steel, in the form of ready-to-fit, hardened guideways to your drawings and also as a semi-finished product to your specifications.

1.2363 machines well and takes hardnesses of up to 63 HRc; good wear properties are achieved with secondary hardening. Larger guideway cross-sections also through-harden well, 1.2363 being the ideal material for hardened guideways over 40 mm thick.
