Headquartered in Manila, Philippines, Isis Metals is a top manufacturer and supplier of quality metal products with expertise in high-grade Incoloy 800HT Forgings. Committed to quality and innovation, we offer heavy-duty, high-performance materials for demanding industrial applications. Incoloy 800HT Forgings are austenitic iron-nickel-chromium alloys well known for their outstanding strength, oxidation resistance, and high-temperature stability. These characteristics make them suitable for applications with extreme temperature and corrosive conditions. We at Isis Metals make sure that every forging adheres to international standards, providing reliability, accuracy, and enhanced performance in industries like power generation, petrochemical, and heat treatment.
Incoloy 800HT Forgings contain 30–35% Nickel, 40–50% Iron, and 19–23% Chromium with small additions of Aluminum, Titanium, and other additives to improve the strength and oxidation resistance. The alloy has good mechanical properties in terms of high tensile and yield strength, weldability, and resistance to oxidation, carburization, and creep at high temperatures. The material is reliable for use in high-temperature environments above 1100°C without structural degradation and mechanical instability. Its superior thermal fatigue and stress rupture resistance is a guarantee of durability and long-term performance under harsh operating conditions.

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 widespread applications in high-temperature, corrosive conditions owing to their strength, heat resistance, and durability. Typical uses are in furnace parts, heat exchangers, and reactor cores, where oxidation and carburization resistance is critical. In petrochemical and power generation sectors, they find application in superheaters, combustion chambers, and gas turbine components. Furthermore, Incoloy 800HT is best suited to heat treatment equipment and industrial furnaces and provides creep and thermal fatigue resistance and stability. Its high durability and corrosion resistance qualify it as the first choice for engineering systems to be used under harsh environmental and thermal stresses.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
