Tanvir Nickel Alloys is a reputable manufacturer and supplier located in Cairo, Egypt, focusing on high-performance industrial fasteners, including top-notch Hastelloy washers. Known for their outstanding corrosion resistance and mechanical strength, Tanvir Nickel Alloys offers solutions specifically designed for tough environments like chemical processing, marine, and aerospace industries. With a strong dedication to quality, innovation, and customer satisfaction, the company guarantees that every washer meets international standards. Their expertise in nickel-based alloys enables them to provide durable and reliable components that can withstand high-stress and corrosive applications both in Egypt and around the globe.
Hastelloy washers are primarily crafted from nickel-molybdenum or nickel-chromium-molybdenum alloys, with popular grades such as C-22, C-276, and B-2. These alloys are known for their excellent resistance to strong oxidizers, acids, and corrosion caused by chlorides. Typically, these washers boast a tensile strength ranging from 690 to 760 MPa and a yield strength of about 280 to 355 MPa, depending on the specific grade. They also provide remarkable thermal stability and toughness, maintaining their integrity even in high-temperature and high-pressure situations. Thanks to their low carbon content, they resist sensitization and intergranular corrosion, ensuring they last in aggressive chemical environments.
