Abstract The effect of solution temperatures (1 000 ℃, 1 050 ℃, 1 100 ℃, 1 150 ℃, 1 200 ℃) on the microstructure, mechanical properties and corrosion resistance of NSSC 2120 duplex stainless steel has been investigated by OM, SEM, tensile and electrochemical experiments. The results showed that, as the temperature increased from 1 000 ℃ to 1 050 ℃, the strip or needle-shaped secondary austenite developed into ferrite, improving the tensile strength and corrosion resistance of NSSC 2120 duplex stainless steel. When the solution temperature went up to 1 150 ℃, both the increment of ferrite content and the tiny uniform austenite induced the tensile strength to reach a peak (632.5 MPa). As the dominant factor, the austenite resulted in a minimum corrosion current density of 2.247×10^-6 μA·cm^-2. When the solution temperature rised to 1 200 ℃, although the ratio of the two phases is close to 1∶1, the tensile strength and corrosion resistance decrease significantly. This is attributed to the austenite sharpening. Compared with the economical duplex stainless steel LDX 2101 and SUS 304 austenitic stainless steel, NSSC steel is excellent in the respect of the cost, the mechanical properties and pitting corrosion resistance.

Key words： economical NSSC 2120 duplex stainless steel solution temperature mechanical property corrosion resistance secondary austenite
