Super Duplex Steel fasteners are greatly appreciated for their great strength and long life. They have very high tensile strength together with excellent resistance to crevice corrosion, stress corrosion cracking, and pitting corrosion. Super Duplex Steel fasteners work well under extreme conditions, whether high or low temperatures, and provide great resistance to chloride-induced SCC. Having a superior strength-to-weight ratio compared to conventional stainless steels, they are best suited for high-pressure corrosive applications but remain strong and lightweight. Their enhanced properties render them a requirement in demanding applications.
