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.
These Incoloy 800H Forgings find extensive use in applications that demand high-temperature strength, oxidation resistance, and long-lasting durability. They’re often utilized in furnace components, heat exchangers, chemical processing equipment, pressure vessels, and piping systems. The alloy is also prevalent in power generation, petrochemical, and marine sectors where performance at high temperatures is crucial. Thanks to its blend of creep resistance, corrosion resistance, and mechanical strength, Incoloy 800H is perfectly suited for challenging high-temperature 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.
