Experimental Study of Mechanical Properties of AISI 1045, AISI 1053 and AISI 4140 Steels

AISI 1045, AISI 1053 and AISI 4140 are the mostly used material for axle shaft of a vehicle. The comparative study of these materials definitely will help in selection of appropriate material for required condition. AISI 4140 has shown greater Young’s modulus, yield strength and tensile strength, but moderate ductility is observed. The lesser ductility of AISI 1053 limits its usage in rear axle shaft. The ductility and Young’s modulus of AISI 1045 is satisfactory, but lower strength is prime concern with it.
