Bilal Nickel Alloys, located in Safat, Kuwait, has earned a solid reputation as a reliable manufacturer and supplier of top-notch nickel alloy products, including Incoloy 800/800H/800HT Flanges. These flanges are celebrated for their outstanding resistance to oxidation, corrosion, and high temperatures, making them a dependable choice for long-lasting performance. Crafted to meet rigorous industrial standards, they’re perfect for critical applications in the chemical, petrochemical, and power sectors. With a focus on precision manufacturing, stringent quality control, and durable materials, Bilal Nickel Alloys delivers flanges that guarantee safety, structural integrity, and efficient operation, even in extreme thermal and mechanical conditions.
Incoloy 800/800H/800HT flanges are mainly made up of nickel (30–35%), iron (39.5–45%), and chromium (19–23%), with small amounts of copper and titanium to enhance stability. The H and HT versions undergo heat treatment to improve their strength at high temperatures and resistance to creep. These flanges showcase remarkable tensile strength (up to 655 MPa), yield strength (275–380 MPa), and elongation, ensuring they maintain their structural integrity in tough conditions. Their exceptional resistance to oxidation, thermal fatigue, and stress corrosion cracking makes them perfect for demanding industrial settings where reliability and durability are crucial.
