Their dedication to quality, prompt delivery, and customer satisfaction has established them as a trusted supplier throughout Oman and the broader Gulf region for high-performance nickel-alloy flange solutions.
Incoloy 800/800H/800HT Flanges are crafted from nickel–iron–chromium alloys, specifically designed to deliver outstanding strength and oxidation resistance even at elevated temperatures. Typically, their composition consists of nickel (30–35%), chromium (19–23%), with iron making up the balance, along with traces of carbon, aluminum, and titanium. The 800H and 800HT grades are enhanced with higher carbon content and controlled levels of aluminum and titanium, which boost their creep and rupture strength. Mechanically, these flanges provide excellent tensile strength, stability at high temperatures, and resistance to carburization and sulfidation. Their remarkable mechanical integrity and thermal stability make them perfect for long-term use in extreme heat environments.
