18CrNiMo7-6 steel

18CrNiMo7-6 | 18NiCrMo5 | 1.6587 |
Case-hardening steel

It is characterised by high case hardness and depth combined with excellent core strength. Recently the grade has been developed further by slightly increasing Carbon and Manganese content and this led to the new designation 18CrNiMo7-6, which is the current official designation for this steel under Euronorm EN 10084, which supersedes DIN17210.
