Corrosion Studies on Stainless Steel 316 and their Prevention – A Review

Abstract

Corrosion is a process that causes a change of metal to chemically stabled form, by reacting with a solution or with the atmospheric air. There are various types of corrosions such as crevice corrosion, intergranular corrosion, stress corrosion, pitting corrosion, galvanic corrosion and uniform corrosion. These types of corrosion and the prevention methods are investigated in this review paper. Stainless steel 316 has excellence in corrosion resistance, due to the presence of molybdenum content. From the literature survey, stainless steel 316 has been tested in various experiments to improve the properties of the material. In the present review, several coating processes and additives which are added on SS 316 to improve the material properties are studied. The advantages of these improvements are reduced cost of change of material, reduced loss of material due to corrosion and increase in materials durability. Hence, stainless steel 316 is used for all corrosion applications which causes less damage and high durability compared with other austenitic steels.

Tribological and Corrosion Performance of CrAlN/CrN Coatings in Artificial Seawater under Varied Nitrogen Pressures

“…Components such as gears, bearings, and propellers in marine engineering equipment face the dual challenges of wear and corrosion due to prolonged exposure to seawater [1][2][3]. Specifically, 316 stainless steel, widely used for its excellent corrosion resistance, shows limitations in corrosive salt-based seawater environments [4]. The synergy of corrosion and wear, particularly studied in simulated environments like artificial seawater, reveals complex interactions during the damage and recovery of the material's passive layer [5][6][7].…”

Comparative Study of Pitting Corrosion in 316L Stainless Steel Using Different Metal Additive Manufacturing Techniques

“…Various factors contribute to the corrosion of 316L stainless steel, including exposure to high chloride environments that result in pitting corrosion [11]. Additivemanufactured steels, similar to conventionally manufactured steels, are prone to corrosion-related damages such as pitting corrosion, which can lead to part failure and catastrophic consequences [12], [13]. The critical pitting temperature, which denotes the minimum temperature at which corrosion pits do not form, has significant implications for the service temperature of additive-manufactured stainless steels [9].…”
