Santner Nickel Alloys is a well-respected manufacturer and supplier of Incoloy 800/800H/800HT Fasteners based in Hamilton, New Zealand. They specialize in providing top-notch fastening solutions that are built to endure extreme industrial conditions. These fasteners are crafted to offer exceptional strength, thermal stability, and corrosion resistance, making them perfect for applications that face high temperatures and harsh environments. Santner Nickel Alloys prides itself on precision manufacturing, rigorous quality control, and adherence to global standards, catering to the needs of industries like power generation, petrochemical, chemical processing, and furnace equipment. Their Incoloy 800 series fasteners promise long-lasting durability and reliable performance, even in the toughest operational settings.
Incoloy 800/800H/800HT Fasteners are primarily made up of nickel (30–35%), chromium (19–23%), and iron, with carefully controlled additions of titanium and aluminum. The 800H and 800HT grades are designed for enhanced high-temperature strength, thanks to increased carbon and optimized Al+Ti content, which boosts creep and rupture resistance. These fasteners are known for their excellent resistance to oxidation, carburization, and chloride stress-corrosion cracking. They maintain a stable microstructure even at temperatures up to 1100°C, ensuring strong mechanical properties like high tensile strength, good ductility, and outstanding resistance to thermal fatigue, making them reliable for prolonged heat exposure.
