ABSTRACT:
A method of producing metal parts having magnetic and non-magnetic portions comprising heat treating an integral workpiece made of a metal capable of acquiring a magnetic structure in the course of aging and of losing the magnetic structure after high temperature tempering. The portions intended for producing the magnetic structure are heated to a temperature of 450.degree. to 980.degree.C, soaked until the magnetic structure is formed and then cooled, and the portions intended for producing a non-magnetic structure are heated to a temperature of between 1000.degree.C and the melting point of the metal so that its integrity is retained and then cooled at a rate that prevents the formation of the magnetic structure.
