The Influence of Varying Aluminium and Manganese Content on the Corrosion Resistance and Mechanical Properties of High Strength Steels

The aim of this paper is to evaluate the influence small variations in chemical composition on corrosion resistance and mechanical properties low-manganese medium manganese high strength steels. Six different steels with content varying from 1.5 4.0 wt.% aluminium 0.008 6.5 were subjected analysis. other subjects for evaluation included effect as a replacement silicon, niobium microalloying heat treatment. non-metallic inclusions localized initiation propagation was also documented. Using potentiodynamic testing, exposure tensile impact it found that improvement associated increasing accompanied by significant deterioration properties. Niobium treatment have no quantifiable anti-corrosion proved be superior nonmetallic terms determining overall experimental
