In a corrosive setting, the harm inflicted on metals due to chemical or electrochemical reactions with their surroundings is termed as corrosion. Even stainless steel isn’t immune to this process if it’s not appropriately chosen for such environments. Stainless steel, often regarded as resistant to rusting, can still fall prey to corrosion under certain conditions. Corrosion can be categorized in several ways depending on its characteristics and causes. One way to classify corrosion is based on the type of interaction occurring between the material and its environment. This leads us to two major types: chemical corrosion and electrochemical corrosion. Chemical corrosion happens when a metal reacts directly with substances in its environment without involving an electric current, whereas electrochemical corrosion involves the flow of electrical currents during the reaction. Another method of categorization is based on the pattern of corrosion. General or uniform corrosion affects the entire surface of the metal evenly, while localized corrosion manifests in specific areas. Examples of localized corrosion include pitting, crevice corrosion, stress corrosion, corrosion fatigue, selective corrosion, and scour corrosion. These forms of corrosion can be particularly dangerous because they might go unnoticed until significant damage has occurred. Corrosion can also be classified according to the environment and conditions where it takes place. Atmospheric corrosion occurs in open-air settings where metals are exposed to oxygen, moisture, and pollutants. Industrial water corrosion happens when metals come into contact with water used in industrial processes. Soil corrosion refers to the degradation of metals buried underground. Acid, alkali, and salt corrosion happen when metals are exposed to these chemicals, often in industrial settings. Seawater corrosion is common in maritime environments, while high-temperature corrosion occurs in extreme heat conditions, including exposure to molten salts or gases.
