Abstract

Changes of mechanical properties and corrosion loss were observed with specimens of 30 Ni-20Cr stainless steels by varying Mo, Si and Cu contents, respectively.
The following results were obtained:
(1) The higher the Mo content, the higher the tensile strength, the yield strength and the elastic limit of forged specimens. But the maximum tensile strength of cast specimens was obtained by addition of 8.8% Mo.
(2) The minimum corrosion loss in a boiling solution of 5wt.% H2SO4 and HCI was obtained by addition of 3-4% Mo, also the minimum grain-boundary corrosion loss was obtained by addition of 3-7% Mo.
(3) Effect of Si and Cu contents on mechanical properties and corrosion loss was less than that of Mo.
