It is important to emphasize that most construction or fabrication of rotating shaft involved some special test for the actual or the proper materials that will be used in such essential work. The test involved class of stainless steel materials that will be of a non magnetic structure.The stainless steel comprise a wide range of iron alloy containing more than 10% chromium.They classified Stainless steel as Austenitic,Ferric,and Martensite,But Austenitic Stainless Steel was selected for rotating shaft machining work, because of its characteristics, The standard composition of austenitic stainless steel are,18% Cr,18% Ni, 18/18 steel. the steel has high resistance to corrosion,good weldability,high toughness,a specially a low temperature and excellent ductility.It is good for production of shaft and non magnetic devices etc.
