Hazlewood Fasteners, located in Canberra, Australia, is a well-respected manufacturer and supplier of top-notch Stainless Steel 347 Stud Bolts. These bolts are specifically designed to perform exceptionally well in high-temperature and corrosive settings, making them perfect for tough industrial tasks. Crafted from high-quality stainless steel and utilizing cutting-edge production techniques, Hazlewood Fasteners guarantees precision, strength, and long-lasting reliability. The Stainless Steel 347 Stud Bolts are known for their outstanding resistance to intergranular corrosion and oxidation, even when subjected to high temperatures. Industries like petrochemical, power generation, aerospace, and marine trust these fasteners for their unmatched durability and consistent mechanical performance.
Stainless Steel 347 Stud Bolts are a type of stabilized austenitic stainless steel fastener that contains 17–19% chromium, 9–13% nickel, and niobium (columbium) to improve resistance to carbide precipitation. This unique composition provides excellent strength at high temperatures, creep resistance, and corrosion protection in oxidizing environments. These bolts boast a tensile strength ranging from 515–700 MPa, a yield strength of about 205 MPa, and good elongation for ductility. Their mechanical stability under stress and resistance to intergranular attack make them perfect for long-term use in heat-exposed and chemically aggressive conditions.
