CORROSION RESISTANCE FOR DIFFERENT TYPES OF STEELS UNDER, ALKALINE SOLUTION

Abstract: Steel gets corroded under the action of chemical reaction with the environment. All the transition metals, iron, copper, zinc and nickel are slower to oxidized, they form passivation layer of oxide that protects the interior. Methods to reduce the activity of the exposed surface are by passivation and chromate conversion [2]. The main aim is to compare the corrosion resistance of different types of steels available carbon steel, stainless steel, galvanized steel, electroplated steel, tool steel, Damascus steel, wootz steel, MMFX steel as a part of that, we compared carbon steel, stainless steel and MMFX steel for research. The tests carried out for these steels are ASTM B117 and ASTM B895 to study the behavior under corrosion. The principal reason for selecting a new reinforcement material for concrete structures is to improve both the life span of the structure and cost effectiveness of the structural system. This paper is focusing on different types of steels under corrosion tests.
