Al Vishwas Nickel Alloys is a highly regarded manufacturer and supplier of Incoloy 800/800H/800HT Fasteners located in Dubai, UAE. They focus on delivering premium fastening solutions engineered to withstand severe industrial conditions. These fasteners are designed to deliver outstanding strength, thermal stability, and corrosion resistance, making them ideal for applications exposed to high temperatures and demanding environments. Al Vishwas Nickel Alloys takes pride in precise manufacturing, stringent quality control, and compliance with international standards, serving the requirements of sectors such as power generation, petrochemical, chemical processing, and furnace equipment. Their Incoloy 800 series fasteners guarantee enduring durability and dependable performance, even in the most challenging operational conditions.
Incoloy 800/800H/800HT Fasteners consist mainly of nickel (30–35%), chromium (19–23%), and iron, along with precisely controlled amounts of titanium and aluminum. The 800H and 800HT grades are engineered for improved high-temperature strength, owing to higher carbon and refined Al+Ti levels, which enhance creep and rupture resistance. These fasteners are recognized for their outstanding resistance to oxidation, carburization, and chloride stress-corrosion cracking. They retain a stable microstructure even at temperatures reaching 1100°C, guaranteeing robust mechanical properties such as high tensile strength, good ductility, and exceptional resistance to thermal fatigue, which makes them dependable for extended heat exposure.
