发明名称 DINING AND/OR SERVING CUTLERY MADE OF FERRITIC STAINLESS STEEL WITH A MARTENSITIC BOUNDARY LAYER
摘要 The invention relates to dining and/or serving cutlery made of a steel material which is formed from a ferritic core with an essentially martensitic boundary layer. In the dining and/or serving cutlery of the invention, the surface hardness of the boundary layer, determined according to the hardness test according to Vickers HV 3, is thereby greater by 30 to 300% than the lowest hardness of the core, likewise measured according to Vickers HV 3.
