Hazlewood Fasteners, based in Canberra, Australia, stands out as a top-notch manufacturer and supplier of high-quality Stainless Steel 17-4 PH Fasteners. These fasteners are crafted for remarkable strength, hardness, and resistance to corrosion. Thanks to their precipitation-hardening process, they deliver outstanding mechanical performance even in high-stress and extreme conditions. The SS 17-4 PH Fasteners blend the excellent corrosion resistance of austenitic stainless steels with the impressive strength of martensitic grades. Their versatility and durability make them perfect for industries like aerospace, petrochemical, marine, power generation, and chemical processing, where reliable fastening solutions are crucial for critical applications.
Stainless Steel 17-4 PH Fasteners consist of 15–17.5% chromium, 3–5% nickel, 3–5% copper, and 0.15–0.45% niobium, with iron making up the rest. Through the process of precipitation hardening, they can achieve a tensile strength of up to 1310 MPa and a yield strength around 1170 MPa, providing exceptional hardness (up to 44 HRC) and fatigue resistance. These fasteners maintain excellent mechanical stability at temperatures up to 315°C and offer corrosion resistance similar to Type 304 stainless steel. SS 17-4 PH Fasteners boast an impressive strength-to-weight ratio, wear resistance, and dimensional stability, even in tough industrial settings.
