Therefore, the development of a new type of corrosion-resistant cast hydrofluoric acid medium stainless steel, and can appropriately reduce the Ni, Mo content, thus greatly reducing the cost of corrosion of steel is the basic starting point of research in this paper, scanning tunneling microscopy imaging techniques., a new cast stainless steel corrosion on the surface of the scanned sample as to obtain a more realistic three-dimensional image information corrosion morphology, the corrosion behavior of steel .30-year-old male,[link widoczny dla zalogowanych], Ph.D.,[link widoczny dla zalogowanych], lecturer. 14 of a \
