Abstract

Corrosion behaviour of two moderately low carbon high strength low alloy steels designated as A (having no Cr and Cu content) and B (having higher Ni, Cr and Cu content) heat treated at different conditions to alter micro-structure phases, have been studied under the simulated condition of sea atmosphere in the laboratory scale in different level of salinity under the influence of neutral pH as well as exposing them in real sea water condition by using electrochemical test. Pre and post corrosion micro-structural studies and quantitative phase analysis were carried out to arrive at structure-stoichometry-corrosion co-relation for designing of steels for industrial application in sea atmosphere.

Keywords
