Their dedication to innovation, customer satisfaction, and global standards of compliance guarantees reliable fastening products that withstand pressure in demanding applications internationally.
Super Duplex Steel Fasteners consist of about 25% Chromium, 7% Nickel, 4% Molybdenum, and traces of Nitrogen. This two-phase microstructure consisting of austenite and ferrite confers higher corrosion resistance, particularly against stress corrosion cracking and pitting. Mechanically, they possess very high tensile strength in excess of 750 MPa, good yield strength, and superior fatigue resistance. These enable the fasteners to serve reliably in high-pressure, chemically aggressive environments in which regular stainless steels would fail.
