Abstract

The GH3535 seamless pipe was developed by hot extrusion and cold rolling. The mechanical properties and corrosion resistance of GH3535 seamless pipe under molten salt environment were tested at different temperatures. The results showed that the extrudability of GH3535 alloy was fine at 1150–1250 ℃, and the mechanical properties of hot-extruded GH3535 alloy pipe were excellent and the microstructure was uniform. The average grain size of GH3535 seamless pipe is about 67 μm. The yield strength of GH3535 alloy pipe is above 200 MPa at 650–700 ℃, the tensile strength is above 480 MPa. The corrosion resistance of GH3535 alloy seamless pipe is also good in high temperature (700 ℃) molten salt environment.
