Abstract
In recent years, more attention is paid to stainless Steel 316L as fracture plate and fixation in human's body.
Present studies are focused on surface and metallurgical properties of this material. Biocompatibelity of this
material and its superior mechanical properties has made it the most demanded biomaterial. In this research,
four different implants are investigated in three stages. Four commercial brands of implants from Germany,
Switzerland, India and Iran are selected. Mechanical tests such as impact, hardness and fatigue are done on
this implant, according to their corresponding standard. Scanning electronic microscope (SCM) is used to
investigate surface fracture, and optical microscope for microstructure, to determine kind of fracture.
Corrosion test is simulated in the body using hank solution to determine implant corrosion. Aim of this
research is quality evaluation with respect to mechanical properties and failure resistance. Moreover,
regardless of brand it is aimed to investigate medical/metallurgical methods to present implant failure inside
the body. Iranian brand is more or less similar to Sweden and German brand, however, Indian brand is not
compatible to medical standards in term of microstructure, chemical composition and mechanical properties.
