Mechanical and chemical properties of the 17-4PH have been investigated after recycled melting. As the result, it has been ascertained that the change of Ni, Cu, Nb, C amount affects the mechanical and chemical properties. It is important to minimize contamination of impurities and to control the amount of Ni, Cu, Nb, C.
