What are the common types of corrosion?

Common types of corrosion include uniform corrosion, pitting corrosion, crevice corrosion, galvanic corrosion, intergranular corrosion, stress corrosion cracking, and erosion corrosion.

What is pitting corrosion?

Pitting corrosion is a localized form of corrosion that creates small holes or pits in a metal surface. It can be especially concerning because damage may be difficult to detect until it has progressed.

What is crevice corrosion?

Crevice corrosion is localized corrosion that occurs in confined spaces or gaps where stagnant solution can collect, such as under gaskets, washers, deposits, or fasteners.

Why is alloy selection important for corrosion resistance?

Proper alloy selection helps ensure that stainless steel or nickel alloy plate can withstand the specific chemical, temperature, mechanical, and environmental conditions of an application.

Types of Corrosion found in Stainless Steel & Nickel Alloy

The corrosion resistance of stainless steel and nickel alloy is dependent on a thin invisible film on the steel surface, the passive film. There are, however, environments that cause permanent breakdown of the passive layer. Under circumstances where the passive layer cannot be rebuilt, corrosion occurs on the unprotected surface. Different media can cause different types of corrosion attack that may vary in nature and appearance. Several forms of corrosion can occur on stainless steels and nickel alloy plates.
