INSTRUMENT MATERIALS

MARTENSITES

Martensitic stainless steels combine high hardness and wear resistance with relatively good toughness. They are resistant to corrosion under atmospheric environmental conditions. They are mainly used for blades and knives in medical applications.

PRECIPITATION-HARDENABLE STEEL

These special alloys have a high formability in the non-hardened state and can achieve very high hardness and strength through precipitation hardening. They are used for complex formed components with very high demands on strength and corrosion resistance.

AUSTENITES

Austenitic stainless steels are characterized in their annealed condition by their high formability combined with very good corrosion resistance. The corrosion resistance can be further increased by adding chromium or molybdenum content. Depending on the nickel content, either higher formability or an a-magnetic material can be achieved. We sometimes find them as implants or connecting elements in our body after surgery.

FERRITES

Depending on the chromium content, ferritic stainless steels can have excellent corrosion properties. They are used wherever good corrosion properties are required but high demands are not placed on formability. By modifying the chemical composition and the manufacturing process, single- or multi-phase structures with special magnetic or other properties can be adjusted and made to measure for the respective application.
