As was stated in the first report, a number of metals superior to 18/8 S. S. in mechanical and physical properties were found among them Nos, 4, 5, 15 and 22, were selected as fundmental compound metals-for ttlhe 2 nd research, taking also the results of corrosion tests into consideration.
The aim of the present research is to find compound metals not inferior to 18/8 S. S. in chemical propety, from the metallurgic stand point especially in corrosion resistance, by the addition of a proper amount of the fourth elements to the fundamental compound metals. As the fourth elements eight kinds were taken into consideration and among them 5 kinds are easily obtainable; there were first selected for investigation.
Of the five elements-Ti, Mo, V, Si, Al, fourkinds of metal were produced by affixing different quantities to each one of them, of which two or three kinds of metal were proved to be superior to 18/8 S. S. not only in mechanical and physical properties, but also in corrosion resistance.
