Abstract The effect of the alloying elements on localised corrosion properties of low-alloy steels has been studied by simulation of an occluded anode cell. Si or Alshowed very strong beneficial main-effect, and at the same time often exerted im-portant influence on the behaviour of other elements. In the latter respect, Si wasthe stronger of the two. The beneficial effect of Cr was marked when the Si con-tent was low (0.1-0.2%), and completely disappeared when Si was increased to0.8-1.0%. Cu behaved somewhat opposite to that of Cr. Mo promoted the benefi-cial effect of Si or Cr, although the main effect of itself alone was unbeneficial.The main effect of Ni is weak, however, it could match with Cu, Mo and Cr-Alto yield beneficial results. With regard to the two elements which were present insteel only in small amount, V was preferable to Nb.
