Duplex Steel 2205 earns its reputation through a remarkable blend of strength and corrosion resistance. This comes from its balanced composition of chromium, nickel, molybdenum, and nitrogen. This specific recipe gives the fasteners a tensile strength nearly double that of standard stainless steels. They also offer exceptional resistance to pitting and stress corrosion cracking, making them incredibly durable under stress and in harsh, corrosive conditions without sacrificing toughness.
