Abstract
In this study, we have examined the possibility to improve the material properties and biocompatibility of the 630 stainless steel for the application of medical instruments. The evaluation of mechanical properties and biocompatibility of the 630 stainless steel were studied by aging, nitriding, SEM measurement, Vicker's hardness, tensile strength and MTT cytotoxicity using IGF cells, respectively. The results showed that the tensile strength and Vicker's hardness of 630 stainless steel was increased with aging and ion nitriding time. The cytotoxicities of the 630 stainless decreased compared with the 420 stainless on MTT cytotoxicity using IGF cells. Ion nitriding of 630 stainless led to an enhanced application of medical instruments and biocompatibility performance.
