Al Vishwas Nickel Alloys is a well-regarded manufacturer and supplier of premium Incoloy 800/800H/800HT Bolts located in Dubai, UAE. They focus on delivering reliable fastening solutions crafted for demanding industrial environments. Owing to their advanced manufacturing techniques and stringent quality inspections, the company creates bolts that stand out in heat resistance, mechanical strength, and corrosion resistance. Built to withstand extreme temperatures and severe conditions, their Incoloy 800 series bolts are ideal for critical applications. Al Vishwas Nickel Alloys serves a range of industries, such as petrochemical, power generation, chemical processing, and heat treatment, supplying durable fastening products that ensure lasting performance, safety, and structural integrity even under the toughest conditions.
Incoloy 800/800H/800HT Bolts consist of nickel (30–35%), chromium (19–23%), and iron, along with precisely regulated quantities of titanium and aluminum to improve stability. The 800H grade contains more carbon, which strengthens its creep and rupture resistance, whereas the 800HT version is fine-tuned with Al+Ti levels for exceptional high-temperature durability. These bolts deliver impressive tensile strength, resistance to oxidation, and stability during prolonged exposure to elevated temperatures. They successfully withstand carburization, chloride stress cracking, and scaling, allowing them to preserve their mechanical integrity across changing thermal conditions and heavy loads, which makes them ideal for challenging industrial applications.
