For Medical Grades, stainless steel, specific grades of Stainless steel – 316 and 316L are predominantly used. By alloying the elements Chromium, Nickel and Molybdenum Stainless steel offers the material scientist and surgeon some uniquely reliable qualities.
- Chromium – heightens the materials scratch resistance and corrosion resistance – perfect for cleaning and sterilization.
- Nickel – provides an extremely smooth and polishable surface – fine details required for machinging precision, high quality products etc. Also important for hygiene.
- Molybdenum – provides hardness after forming and is great for sharp cutting edges – scalpel
Note – In some rare cases the bodies immune system has been known to have an adverse reaction (both cutaneous and systematic) to the nickel content in some stainless steels. In cases like this, Titanium may be used as a substitute for Stainless Steel. However, with Titanium comes a more costly solution. Often, Stainless steel is used for temporary implants and the more expensive, titanium may be used for permanent implants.
