Martensitic stainless steels

The martensitic structure obtained in these alloys after quenching gives them high yield and tensile strength and high hardness. Martensitic stainless steels contain between 11.5 and 18% chromium and a carbon content higher than 0.1%. These alloys are used in the quenched and tempered condition, giving the end product a hardness perfectly adapted to the intended utilization. Depending on the grade concerned, principal applications are e.g. cutlery or surgical instruments.
