1. 18CrNiMo7-6 steel introduction
It is a case-hardening steel that is similar to 17NiCrMo6-4, but it has a more elevated hardenability, because of the higher content of chromium and manganese. It is suitable for thick parts or with an elevated diameter, which require a high resistance and toughness at heart. After case-hardening, hardening and stress relief tempering.
