Tanvir Nickel Alloys stands out as a top-notch manufacturer and supplier located in Cairo, Egypt, focusing on high-quality Incoloy 800/800H/800HT Nuts that are engineered for exceptional performance in tough environments. These nuts are celebrated for their remarkable strength, resistance to corrosion, and stability even at high temperatures. At Tanvir Nickel Alloys, precision in manufacturing and rigorous quality control are paramount, adhering to international standards to deliver durable and dependable fastening solutions. The company’s Incoloy 800 series nuts find their way into various industries, including petrochemical, power generation, and chemical processing, where performance, durability, and safety are absolutely crucial.
The Incoloy 800/800H/800HT Nuts are primarily made up of nickel (30–35%), chromium (19–23%), and iron (the balance), with small amounts of aluminum, titanium, and carbon added in. This unique composition grants them excellent resistance to oxidation, carburization, and high-temperature corrosion. On the mechanical side, these nuts boast a tensile strength of around 600 MPa, a yield strength of about 275 MPa, and an elongation rate between 30–40%. They excel in creep and rupture strength while maintaining toughness and dimensional stability, even when the heat is on.
