Incoloy 800HT is an ultrahigh-temperature-capable nickel-iron-chromium alloy that has been developed for improved creep and rupture properties at high temperatures. Kanish Metals provides precision-forged components meeting international standards, guaranteeing strength, mechanical integrity, and corrosion resistance. Supplying industry sectors including petrochemical, power generation, heat treatment, and chemical processing, Kanish Metals is renowned for quality, customization, and punctual delivery in the UAE and international markets.
Incoloy 800HT is a heat-treated variation of Incoloy 800H, with closely controlled levels of aluminum and titanium and optimized heat treatment to maximize high-temperature strength and thermal degradation resistance. The material generally has 30–35% nickel, 19–23% chromium, and minor additions of aluminum and titanium. It has very good mechanical properties, tensile strength near 600 MPa, and outstanding resistance to oxidation, carburization, and sulfidation. Incoloy 800HT has structural stability up to 1100°C and is well suited for long-term exposure in high-temperature, high-stress service.

To determine if Incoloy 800HT Forgings meet your specific needs, assess their high-temperature resistance, oxidation, and carburization properties against your application requirements. Consulting with a supplier for detailed material specifications and testing options can also ensure compatibility.
The ideal temperature range for forging Incoloy 800HT is between 2100°F (1149°C) and 2300°F (1260°C). This range ensures optimal workability, mechanical properties, and maintains the material's strength and resistance to oxidation.
Temperature control is crucial for maintaining the desired mechanical properties of forged Incoloy 800HT, as overheating or insufficient heating can lead to reduced strength and ductility. Proper temperature management ensures optimal grain structure, resistance to oxidation, and overall performance in high-temperature applications.
Incoloy 800HT Forgings have numerous applications where strength, heat resistance, and corrosion resistance are critical. Some common applications are parts for heat exchangers, furnace manifolds, petrochemical process units, reformer tubes, superheater and reheater tubing, and power plant equipment. The very good creep resistance and structural integrity of the alloy in long-term thermal exposure make the alloy suitable for high-temperature pressure vessels and thermal processing equipment. Incoloy 800HT forgings find application in nitric acid and organic chemical environments as well, providing a high service life in sensitive operations where other materials would suffer degradation or failure.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
