ink rolls are used to guide the steel sheets into the molten zinc bath in
continuous hot dip galvanizing line. They are usually made of AISI
SS 316L material due to its properties like high corrosion resistance, low
tendency towards carbide precipitation and hot strength characteristics. High
temperature immersion corrosion test using potentio-dynamic polarization set
up was performed to study the dissolution rate of AISI SS 316L material in pure
zinc bath and zinc-0.2 wt % aluminium bath at three different temperatures:
460 °C, 480 °C and 500 °C for 5 hours. It was observed that dissolution rate of
AISI SS 316L was maximum at 480 °C with negative open circuit potential with
respect to graphite and minimum at 500 °C with positive open circuit potential
with respect to graphite. Dissolution rate of AISI SS 316L material was found
more in pure zinc bath compared to zinc-0.2 wt % aluminium bath due to
formation of protective and adhesive intermetallic inhibition layer during test
