Precise and durable materials are of crucial importance in modern medical technology. A key material in this field is steel, which is used in various forms and alloys to meet the stringent requirements of medicine. From surgical instruments to implants – steel plays a key role in making medical procedures safer.

Medical technology has made enormous progress in recent decades, and steel is one of the main materials that has made this development possible. Whether in surgical instruments or as a component of implants, steel offers the necessary reliability that is essential in medicine.

As a reliable material that can be easily disinfected, steel plays an important role in medicine and medical technology.

Requirements for medical steel

Extremely high requirements apply to the manufacture of medical devices and implants. These can be divided into five main categories: Harmlessness, biological and mechanical compatibility, functionality and handling. Medical steel must be non-toxic, antigen-free and biocompatible in order to prevent reactions in the body. Mechanical strength and corrosion resistance are also crucial to withstand the high stresses to which surgical instruments and implants are exposed. In addition, these materials must be easy to clean and sterilize in order to comply with strict hygiene regulations.

Two main categories: Medical steel and implant steel

Two main types of steel are used in medical technology: Medical steel and implant steel. Medical steel, also known as surgical steel, is usually a martensitic stainless steel and is particularly hard, stiff and resistant to heat and acids. These properties make it ideal for surgical instruments that require precise cuts and have to withstand many sterilization cycles.

Implant steel, on the other hand, is mainly used in prostheses and other implantable medical devices. These stainless steels undergo an austenitic manufacturing process, which makes them particularly strong and corrosion-resistant. As implants are exposed to extreme conditions in the human body, they must not only be able to withstand mechanical stress, but also be biocompatible. This means that the body accepts the implants without rejecting them as foreign bodies.

Why steel and not another material?

Steel offers several advantages: In addition to the obvious mechanical advantages such as strength and hardness, steel also offers benefits such as corrosion resistance and biocompatible properties, which are crucial for use in medicine. Another feature is the hygienic surface, which prevents the growth of bacteria and thus prevents infections.

In recent years, new alloys and surface coatings have also been developed to further improve the already excellent properties of medical steel and implant steel. These advances help to increase the durability and safety of medical devices and implants while minimizing the risk of complications.
