Stainless steel, made by mixing iron and carbon produces strong discs, although its mechanical properties may be inferior to its metallic counterparts. Since most artificial discs approved for use in the US have only been available for about a decade or less, more time is needed to study the long-term effects of these materials on the body.
316L stainless steel is very important for the security and service lifetime of the nuclear plant. It was. reported that VHCF degradation was different from conventional fatigue up to ten million ...
Artificial heart valves can be classified into mechanical and biological. We have three types of mechanical heart valves: caged ball, tilting disc and bileaflet. Mechanical heart valves are made from various materials. They may be produced from metals, ceramics and polymers, e.g.: stainless steel, t …
