  • Patent number: 6033625
    Abstract: Improved parts of electronic apparatus made of ferritic free cutting steel, which enjoy high precision in size given by good machinability and free from trouble caused by corrosion of metal due to generation of sulfides. The material steel has an alloy composition consisting essentially of, by weight %, C: up to 0.1%, Si: up to 2.0%, Mn: up to 2.0%, Cr: 19-25% and S: 0.20-0.35% and the balance of Fe and impurities. The parts made by machining can be used without being passivated. The steel may contain, further to the above alloy components, one or more from the following groups: 1) Mo: up to 4.0%; 2) one or more of Pb: up to 0.4%, Bi: up to 0.3%, Te: up to 0.3%, Se: up to 0.4% and Ca: up to 0.3%; 3) one or both of B and Mg: 0.001-0.02%; 4) one or both of Cu and Ni: 0.1-4.0%; 5) one or more of Nb, Ta, Ti, V, W and Al: 0.01-0.50%; and 6) O: 0.01-0.04%.
