Wear assessment on AISI 410 steel by tempering process for constant load and speed sustainable applications

Abstract

Stainless steels are readily available and inexpensively priced on the market. The reasonable corrosion resistance of AISI 410 martensitic stainless steel has made it a popular choice. Although it is not very ductile, AISI 410 martensitic stainless steel is very strong, robust, and resistant to wear. Due to their exceptional hardness and resistance to wear, martensitic stainless steels were favored for certain limited applications. Therefore tempering was chosen to improve the ductility by keeping stability in brittleness and hardness. The samples were underwent with tempering at 230°C, 430°C, 630°C and designated as T1, T2,T3 respectively. The samples were made cylindrical in shape with 12 mm diameter, length of 42 mm. A pin-on disc wear test instrument was used to assess the material's resistance to wear for all the samples. A sample that has not been treated is set aside for results comparison. All the samples were undergone with hardness measurement and Scanning electron microscope to examine the microstructure and the resulting data were compared.
