Uniform corrosion occurs on the surface of marine EH40 steel plate in extremely cold environment without cryogenic treatment, and a uniform and dense corrosion layer appears on the surface of the sample.
However, pitting corrosion on the surface of the EH40 steel plate after -80 ℃ cryogenic treatment increases the weight loss, and the corrosion rate increases from 1.15 mm/a to 1.33 mm/a, with an increase of about 15.6%. The lower ambient temperature has a certain influence on the corrosion resistance of EH40 steel plate in extremely cold environment.
