Nickel-Based Corrosion-Resistant Alloys

Nickel-based corrosion-resistant alloys are a class of advanced metallic materials engineered primarily to withstand extreme corrosive environments. Their foundation is a nickel (Ni) matrix, which is inherently resistant to many corrosives, alloyed with other key elements—primarily chromium (Cr), molybdenum (Mo), and sometimes copper (Cu) and nitrogen (N)—to create a versatile and powerful family of materials for the most aggressive chemical and industrial applications. They are the go-to solution when stainless steels are no longer sufficient.
