Physicochemical properties forming of wire made of AISI 316L for urology

摘要

Development of modern urology requires improvement of surgical techniques, which in turn determines the necessity to produce modern equipment and a range of auxiliary materials for treatment. One should mention here guide wires. Thanks to their application during operation, it is possible to insert endoscopes, catheters or urological stents efficiently. Both, guide wires and stents. are made of stainless steel. They must feature suitable application properties for individual applications (among other things mechanical properties and resistance to corrosion in urinary environment, which features depend to a great extent on wire production technology and determination of physical and chemical characteristics of their surface layer) [1-4].
