Aisha Nickel Alloys, located in Muscat, Oman, stands out as a top manufacturer and supplier of high-performance Incoloy 800, 800H, and 800HT forged fittings. These fittings are celebrated for their remarkable resistance to oxidation, carburization, and thermal fatigue, making them perfect for even the toughest industrial applications. With a strong focus on quality, Aisha Nickel Alloys guarantees precision in manufacturing, rigorous testing, and prompt delivery. Their Incoloy 800 series forged fittings are known for their dependable performance in high-temperature and corrosive settings, which is why they’re a go-to choice in the chemical processing, petrochemical, power generation, and marine sectors across Oman and the wider Middle East.
The Incoloy 800/800H/800HT forged fittings are primarily made up of nickel (30–35%), with iron making up the balance, and chromium (19–23%), along with small amounts of carbon, manganese, silicon, and copper. The 800H and 800HT versions are designed with controlled carbon levels to enhance their strength at high temperatures. These fittings boast impressive tensile strength, yield strength, and creep resistance when exposed to elevated temperatures, along with exceptional corrosion resistance in both oxidizing and mildly reducing environments. Their toughness and ductility make them perfect for forging into fittings that can handle thermal cycling and mechanical stress without losing structural integrity or long-term performance.
