Abstract

Abstract

According to the standard（GB/T 15260-1994）, the experiments of intergranular corrosion of homemade and imported Alloy 690 used in SG tubes are conducted in boiling HNO₃ solutions and boiling H₂SO₄-Fe₂（SO₄）₃ solutions. The intergranular corrosion rate and microstructure of tested specimens are obtained from the experiments. It is found that the homemade Alloy 690 has excellent intergranular corrosion resistance, and the intergranular corrosion resistance of homemade Alloy 690 is generally better than that of imported Alloy 690.
