High - grade 2205 duplex coil, corrosive use

One of the most significant advantages of 2205 stainless steel coil is its exceptional resistance to corrosion. The high chromium content provides a robust passive layer that protects the steel from aggressive environments, including chloride-rich conditions. This makes it an ideal choice for applications in coastal areas or environments where exposure to saltwater is a concern. Additionally, the presence of molybdenum enhances its resistance to pitting and crevice corrosion, ensuring longevity and reliability in even the harshest conditions.
