The surgical instruments available today are made of stainless steel, an ideal material in many respects. It is rust resistant, can be sharpened and keeps a sharp edge.

In addition to all the efforts made by manufacturers to select the best steels for the instruments, users must follow the maintenance, handling and use advice. Stainless steel instruments are usually passivated. Passivation is a process that reinforce the protective layer of chromium oxide on the surface of the instrument, thus preventing any possibility the risk of corrosion. As passivation is a very important phenomenon, it would be good to go into a little more detail.

When instruments are in contact with the ambient air or certain oxidising agents, a thin protective film forms on the clean surface of the instrument. This is called the protective passivation layer.

– Very high degree of purity
– High grain homogeneity
– Fatigue resistance
– Rigorous amagnetism for MRI examinations without image deviation

Recommended for:
– High mobility hip prostheses
– Very thin and elaborate screws
