Effect of SO42− and Cl− anionic attack on the localized corrosion resistance and morphology of 409 ferritic stainless steel

Stainless steels are materials used in specific applications where a good corrosion resistance property combined with high material mechanical resistance are required. The shot peening process has been used in order to improve the mechanical properties of metallic surfaces. Besides, it might has influence on the material electrochemical behavior, depending of the used parameters in the operational process. The purpose of this study is to evaluate the effect of the shot peening process in the corrosion resistance of AISI 430 ferritic stainless steel. Wettability test, atomic force microscopy (AFM), open circuit potential (OCP) and potentiodynamic polarization curves have been used in order to evaluate the behavior of AISI 430 ferritic stainless steel after the shot peening process. The aim of this study was to demonstrate the influence of shot peening on the surface properties of ferritic stainless steel AISI 430 and correlate them with the reactivity of the surface. The results showed that the shot peening process, contributes to avoid the localized corrosion resistance of the AISI 430 ferritic stainless steel.

Oxidation And Corrosion

Abstract ATI 409HP (UNS S40900) ferritic stainless steel was introduced by ATI Allegheny Ludlum to provide improved oxidation and corrosion resistance for automotive exhaust systems in comparison to carbon steel. The alloy was designated "MF-1", indicating its end use: automotive mufflers. The good fabricability of this alloy, combined with its basic corrosion resistance and economy have significantly broadened the utility of ATI 409HP stainless steel. ATI 409HP consists of four grades: UNS S40900, S40910, S40920, and S40930. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on high temperature performance and corrosion resistance as well as forming, machining, and joining. Filing Code: SS-1135.
