Abstract

The effect of heat treatment of duplex stainless steel 2507 on its corrosion in artificial saliva is studied. The microstructure of the steel is analyzed using scanning electron microscopy and x-ray diffractometry. The hardness and the corrosion resistance of the alloy are determined and potentiodynamic measurements are performed. An optimum mode of heat treatment is suggested for raising the corrosion resistance of steel 2507.
