The Fasteners Mart, Mumbai, India, is a premier industrial fastener manufacturer and exporter of high-quality fasteners. It is well-known for its quality products, precision engineering, and customer-focused service. It supplies fasteners to petrochemical, power generation, oil & gas, and marine industries. Its one of the popular products is the Incoloy 800/800H/800HT Fasteners in bolt, nut, washer, screw, and stud shapes. Made from nickel-iron-chromium alloys, these fasteners are used for high-temperature strength, superior oxidation resistance, and long-term structural stability in severe environments.
Incoloy 800 series fasteners consist of Nickel (30–35%), Chromium (19–23%), and Iron (balance) with small amounts of Titanium, Aluminum, and Carbon. Grades 800H and 800HT contain increased carbon content and controlled grain sizes to enhance creep and rupture resistance. These fasteners provide tensile strength up to 600 MPa and are resistant to oxidation, carburization, and scaling even at high temperatures. Their density is approximately 7.94 g/cm³, and they exhibit very good mechanical properties even at temperatures of up to 1100°C, which makes them suitable for thermal-intensive environments.
