Chuck Metals stands out as a top manufacturer and supplier in Singapore, specifically on Pulau Ujong, where they offer high-quality Incoloy 800H Forgings. These forgings are celebrated for their remarkable strength, resistance to corrosion, and ability to perform well at high temperatures. Crafted from a nickel–iron–chromium alloy, with carefully controlled amounts of carbon and aluminum–titanium, these products are designed to enhance creep and rupture strength. Chuck Metals is committed to precise manufacturing that meets international standards, providing a variety of shapes and sizes to serve critical industries. Their Incoloy 800H Forgings are a trusted choice in sectors like petrochemical, refinery, power generation, and furnace components.
Incoloy 800H Forgings mainly consist of nickel (30–35%), chromium (19–23%), and iron as the primary component, with carbon levels ranging from 0.05–0.10% and aluminum (0.15–0.60%) and titanium (0.15–0.60%) added for extra strength. They boast a tensile strength of about 520 MPa and a yield strength of around 205 MPa, all while maintaining excellent ductility and structural stability at temperatures reaching up to 1100°C.

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 forgings find extensive applications in heat-treating equipment, industrial furnaces, petrochemical processing units, steam superheaters, and heat exchangers. Their outstanding resistance to oxidation, carburization, and harsh chemicals makes them perfect for high-temperature structural uses. Incoloy 800H Forgings are also highly regarded in the oil & gas, marine, and power industries for their long-lasting service life, reliability, and consistent performance even in extreme operating conditions.
