Abstract

The aim of the project reported here was to develop a low alloy, structural steel that will provide improved corrosion resistance for continuous exposure to marine environments, particularly in splash and low water zones. It was required that the steel should be suitable for manufacture by existing production methods. In addition, the steel is to be readily weldable, and have acceptable, mechanical properties and microstructure in the as-rolled condition. The base composition of the steel was 0.07% C, 1.0% Mn, 0.02% P, 0.015% S, 0.03% Nb with additions of silicon of 1% and 1.9% and chromium of 0.25% and 0.6%. Four Si-Cr steels, produced as four tonne arc furnace melts, were rolled under production conditions to channel sections. The channels were assessed in terms of their microstructures, mechanical properties, welding and corrosion performance. The reference steel used for comparison was a standard BS4360 Grade 50, high yield strength of piling quality.
