Incoloy 800 Fasteners

Vision Alloys is a leading manufacturer and supplier of Incoloy 800 fasteners, Incoloy 800H fasteners, and Incoloy 800HT fasteners, providing industries needing exceptional resilience to corrosive conditions and high temperatures. Incoloy fasteners find great usage in power plants, petrochemical factories, heat exchangers, and furnace components. High durability and dependability abound from the Incoloy 800 series fasteners, which also resist oxidation and carburization at high temperatures. Our product line includes Incoloy 800 bolt nuts, Incoloy 800H flat spring washers, and Incoloy 800HT bolt nuts and screws, available in a range of sizes and specifications to meet varied industrial applications.


Incoloy 800, 800H, and 800HT are perfect for high-temperature uses because of their mechanical qualities improved by their chemical makeup. The superior oxidation resistance these alloys offer consists mostly of nickel (30.0 – 35.0%), iron (balance), and chromium (19.0 – 23.0%). Moreover, tiny quantities of titanium (0.15–0.60%) and aluminum (0.15–0.60%) aid in strengthening and stabilizing. The carbon content varies significantly for higher creep resistance at high temperatures; Incoloy 800H and 800HT include 0.05–0.10% and 0.06–0.10%, respectively.


The mechanical qualities of the Incoloy 800 fasteners qualify them for rigorous industrial use. Among Incoloy fasteners, tensile strength of 520 MPa (75 ksi), yield strength of 205 MPa, and elongation of 30% prevail. Usually falling on the Rockwell B90 range, the hardness guarantees outstanding wear resistance and strength. Applications needing mechanical strength and thermal stability will find Incoloy 800, 800H, and 800HT fasteners to be a perfect fit for these characteristics.
