Assessment of wear behavior analysis on normalized martensitic stainless steel for sustainable applications

Abstract

An alloy of iron and chromium is called stainless steel. The compositionratio of stainless steel will vary depending on the grade required and the intended use of the steel, although it must contain at least 0.5% chromium. Numerous applications exist for stainless steel in the industrial and consumer markets because of its superior corrosion resistance, high strength and good appearance aesthetic wise. Because of the chemical composition, martensitic steel is a kind of stainless steel that can be strengthened, hardened with heat and ageing processes. Because of these techniques, Martensitic steel is stronger than other kinds, which makes it a good option for manufacturing mechanical valves, turbine parts, medical equipment applications. AISI 410 martensitic stainless are strong and wear resistant one. The usage of this material is limited because of its hardness. For enhancing the ductility, these steels were subjected to normalizing process at 740°C, 840°C, 940°C and designated as N1, N2, N3 respectively. The samples were made cylindrical in shape with 11 mm diameter, length of 40 mm. The outcomes of the results like measurement of hardness, loss of wear were noted down and comparisons of microstructures with all the samples were carried out.
