What are Duplex Steel Fasteners?
Duplex Steel Fasteners are specialized fasteners made from duplex stainless steel, a unique alloy that blends the best properties of both ferritic and austenitic stainless steels. Known for their affordability, durability, and superior corrosion resistance, these fasteners are highly versatile and are often used in harsh environments where traditional fasteners may fail. The high chromium content in duplex steel, along with a moderate amount of nickel, gives these fasteners excellent corrosion resistance, particularly against localized issues such as crevice and pitting corrosion, as well as stress corrosion cracking. Because of these characteristics, Duplex Steel Fasteners are favored for applications that require enhanced performance and longevity, making them a better choice than standard fasteners in many industrial settings.
