Abstract

Microstructure of a marine steel with a modified AISI-1004 composition was controlled by cold rolling and heat treatment, which corrosion behavior in an artificial sea water was electrochemically determined for the each deformation direction. The lowest corrosion rate of the surface normal to the rolling direction is related t the (111) fiber structure. Additional annealing at $550^{\circ}C$ for 24 hours improves the corrosion rate which is related to re-crystallization and reduction of (111) concentration.
