Duplex and Super Duplex UNS S31803 Stud Bolts

UNS S31803 Stud Bolts are specialized high-strength fasteners manufactured from a Duplex Stainless Steel (also known as Alloy 2205), known for its remarkable corrosion resistance and excellent mechanical properties. Zeron Fasteners specializes in supplying and manufacturing premium quality UNS S31803 Stud Bolts that are essential in environments where traditional materials fail. The material's superior yield strength (approximately twice that of standard austenitic stainless steel) and exceptional resistance to chloride stress corrosion cracking makes these fasteners indispensable. Typical application includes marine engineering, chemical and hydrocarbon processing equipment, and heat exchangers.
