SELECTION OF MATERIALS

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.

A DESIGN OF PUMP SHAFT INTRICATE AND PROCESS MACHINING.

The design of a heavy duty pump shaft may involved some intricate standard and professional cases, that may be reviewed to meet the necessary requirements for the production.And the presentation of the blue print (drawing) including the interpretation of the sectional details and the process adaptation and production.Such factors that militates the design must be taken into obvious consideration to with stand the impact of the load and the substance to which the design is investigated.The temperature and limitation shall also be determined..and all the load factors must be evaluated for effective performance. hence it shall be able to overcome the whirl velocity of the fluids..
