Bilal Nickel Alloys, based in Safat, Kuwait, stands out as a top manufacturer and supplier of high-performance nickel alloys, with a focus on precision-engineered fasteners. Their standout products include Incoloy 800/800H/800HT Bolts, crafted to provide outstanding resistance to oxidation and corrosion, even at high temperatures. Known for their strength, durability, and reliability, these bolts are perfect for tough industrial settings. Bilal Nickel Alloys maintains strict quality control, employs advanced manufacturing techniques, and follows international standards, making their Incoloy bolts a trusted option for the chemical, petrochemical, and power industries that need components to withstand extreme thermal and mechanical conditions.
Incoloy 800/800H/800HT bolts are primarily made up of nickel (30–35%), iron (39.5–45%), and chromium (19–23%), with small amounts of copper and titanium added for better stability. The “H” and “HT” versions are heat-treated to enhance their creep and tensile strength at elevated temperatures. These bolts boast impressive mechanical properties, including high tensile strength (up to 655 MPa), excellent yield strength (around 275–380 MPa), and remarkable elongation, which makes them highly resistant to thermal fatigue, stress corrosion cracking, and oxidation. This unique combination ensures they perform reliably in high-temperature, corrosive environments.
