Plasticity investigation of Medium Carbon Steel ( AISI CK45 ) treated by Quenching media

This paper goals to investigate the plasticity of Medium Carbon Steel (AISI CK45) treated by three of Quenching ( Salty . Acid and Base ) media , the sample was selected with length (100 mm) and (10 mm) diameter , has been prepared in the form of a shaft , (24) samples were immersed in different media for (100) hours, the conclusion that the quenching process of ( AISI CK 45 ) at salty (NaCl) media at a concentration of (5%) will give a high plasticity .
