Aung Metals, a reputable manufacturer and supplier located in Naypyidaw, Myanmar, has built a solid reputation for crafting high-quality Incoloy 800H Forgings. These forgings are known for their remarkable strength, stability, and resistance to corrosion, especially in high-temperature settings. Designed specifically for demanding industrial environments, they excel in resisting oxidation, carburization, and creep. Aung Metals is committed to ensuring that each forging adheres to strict international standards, guaranteeing products that boast excellent dimensional accuracy, mechanical integrity, and long-lasting reliability. Incoloy 800H Forgings from Aung Metals are a go-to choice in the power generation, petrochemical, and heat treatment sectors due to their consistent performance.
The composition of Incoloy 800H Forgings includes 30–35% nickel, 19–23% chromium, and the remainder being iron, along with trace amounts of aluminum, titanium, and carbon. The increased carbon content, compared to Incoloy 800, significantly boosts creep and rupture strength at high temperatures. These forgings typically achieve a tensile strength of about 520 MPa and a yield strength of 205 MPa, maintaining excellent metallurgical stability even under prolonged heat exposure. The alloy’s unique makeup provides exceptional resistance to oxidation and carburization in harsh environments.

The ideal temperature range for forging Incoloy 800H is between 2100°F and 2250°F (1149°C to 1232°C). This range ensures optimal workability and preserves the material’s mechanical properties.
Post-forging operations for Incoloy 800H typically include annealing to relieve stress and enhance ductility, followed by heat treatment to achieve desired mechanical properties. Surface cleaning and inspection for defects are also essential to ensure quality.
To determine if Incoloy 800H Forgings meet your specific needs, review material specifications, including composition and mechanical properties, and consult with suppliers for customized testing or performance data. Additionally, consider your application's temperature, corrosion, and mechanical requirements.
Incoloy 800H Forgings are widely utilized in industries that require both durability and heat resistance. They are perfect for creating furnace components, heat exchangers, pressure vessels, petrochemical heaters, and piping systems. With the ability to endure temperatures up to 1100°C, they are well-suited for industrial furnaces, superheaters, and thermal processing systems. Additionally, Incoloy 800H Forgings are employed in refineries, nuclear power plants, and chemical processing equipment. Their outstanding mechanical properties and resistance to high-temperature corrosion ensure they perform reliably in even the toughest industrial applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
