Abstract

The corrosion behaviour of 316LVM in NaCl solution steel has been investigated. Large scale polarization measurements and etching tests in V2A solution showed that the hydrostatically extruded (HE) 316LVM steel had a lower corrosion resistance than specimens in the as received condition. Small area measurements were carried out in order to determine the sites that were responsible for the decreased corrosion resistance of the HE 316LVM steel. Tests on cross sections parallel to the HE direction, showed better corrosion resistance than on cross sections perpendicular to the HE direction. These observations indicate, in combination with SEM and AFM measurements, that the inclusions which were deformed during HE, can trigger the onset of corrosion on HE 316LVM steel.
