Aung Metals, located in Naypyidaw, Myanmar, has built a solid reputation as a reliable manufacturer and supplier of top-notch **Incoloy 800HT Forgings**. Renowned for their precision and durability, Aung Metals crafts nickel-iron-chromium alloy forgings that excel in high-temperature and corrosive settings. Incoloy 800HT, a high-temperature variant of Incoloy 800, is particularly prized for its outstanding oxidation resistance, impressive creep and stress-rupture strength, and its ability to withstand carburization and nitridation. Thanks to advanced forging techniques and rigorous quality control, Aung Metals guarantees that its Incoloy 800HT Forgings deliver dependable, long-lasting, high-performance solutions for industries like chemical processing, power generation, and petrochemicals.
These forgings are primarily made up of iron (30–35%), nickel (38–46%), and chromium (19–23%), along with trace amounts of titanium, aluminum, and other elements. This unique blend gives them remarkable mechanical strength, excellent resistance to high-temperature oxidation, and stability during thermal cycling. In terms of mechanics, these forgings boast a tensile strength ranging from 585 to 690 MPa, a yield strength between 275 and 380 MPa, and impressive elongation and toughness, making them perfect for high-stress, high-temperature industrial applications.

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 find their place in various industries that demand high-temperature strength, corrosion resistance, and durability. They are particularly suited for heat exchangers, furnace components, boiler tubes, petrochemical reactors, and piping systems. Moreover, they are commonly used in power plants, chemical processing facilities, and refineries where resistance to creep, oxidation, and thermal fatigue is essential. With their blend of mechanical strength, thermal stability, and corrosion resistance, Incoloy 800HT Forgings are the go-to choice for challenging high-temperature engineering and industrial tasks.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
