摘要 A profiled element suitable for repeated deformation and relaxation, which profiled element is made from a case hardened stainless steel including at least 9% chromium and up to 6% nickel which profiled element has a material thickness in the range of from 0.2 mm to 3 mm and a nitrogen martensitic case with a case depth in the range of from 10 μm to 50 μm and a surface hardness of up to 750 HV0.05 and to a method of case hardening a workpiece made from a stainless steel including at least 9% chromium and up to 5% nickel, which workplace has a material thickness in the range of from 0.2 mm to 3 mm. The profiled element may be a fixing element for fixing a bearing element and a fastening element against each other, and the method is suited in the manufacture of the fixing element.
