Despite the rise of many biomaterials available in modern medicine, nowadays, stainless steel is one of the most frequently used biomaterials for internal fixation devices and surgical instruments. The biocompatibility of medical grade stainless steel has been proved by successful human implantation for decades. However, because exist the possibility of health hazards caused by nickel toxicity, nickel-free stainless steels are slated to be developed as the next generation of surgical stainless steel. The objective of this work is to fabricate a Lotus-type porous high nitrogen austenitic stainless steel without nickel and to evaluate its physical properties like: microstructure, porosity and average pore size.
