Combines the effects of tensile stress and a corrosive environment, leading to cracking. To avert SCC, use stress-relief treatments, reduce residual stresses, select SCC-resistant materials, and control the corrosive environment.

Characterized by a uniform loss of material across the surface, often due to a reaction with the environment. To prevent it, apply protective coatings, use corrosion-resistant materials, or control the environment (e.g. reduce humidity).

Also known as 'dealloying', this occurs when one metal is removed from an alloy. To prevent selective leaching, use more homogeneous materials, apply appropriate heat treatments, or alter the corrosive environment.

Occurs in confined spaces where stagnant solution is present, setting up differential aeration cells. Prevent it by avoiding design that allows for crevices, using sealing compounds, and proper material selection.

This type occurs along the grain boundaries of an alloy, often due to impurities or precipitates at the grain boundaries. Prevent it by using low-carbon alloys, stabilization of the alloy elements, and post-welding heat treatments.

Occurs at high temperatures and involves complex chemical reactions between materials and their environments. Prevent by material selection (high-temperature resistant), use of coatings or barriers, and controlling the atmosphere (e.g. low oxygen environments).

Accelerated corrosion due to fluid motion, typically resulting in grooving, gullies, and wave patterns. Use erosion resistant materials, alter fluid dynamics, and apply protective coatings to prevent.

Features small, localized areas of corrosion that lead to the creation of pits. It's often caused by localized chemical or mechanical damage to a protective oxide layer. Prevent by using pit-resistant materials, proper design to avoid crevices, and maintaining proper chloride levels in the environment.

Occurs when two different metals are in electrical contact in a corrosive environment, leading to one metal corroding faster than the other. To prevent it, use the same metal for all parts, or use coatings, or insulating materials to separate dissimilar metals.
