One of the top producers and suppliers of premium-grade Incoloy 800H Forgings, made for high-temperature and high-stress industrial settings, is Dhruv Metals, based in Hyderabad, India. Forgings of Incoloy 800H are widely used in vital applications in the petrochemical, power generation, and heat treatment industries because of their remarkable strength, oxidation resistance, and structural stability. Custom sizes and configurations are available for these forgings, which are manufactured by Dhruv Metals with accuracy and rigorous adherence to international standards. The company provides forged components that guarantee performance, safety, and durability under demanding thermal and corrosive operating conditions, supported by cutting-edge technology and skilled craftsmanship.
Nickel (30–35%), chromium (19–23%), and iron (39.5% min) make up Incoloy 800H Forgings. For increased high-temperature strength, aluminium, titanium, and carbon (up to 0.10%) are added. At high temperatures, this alloy is resistant to oxidation, carburisation, and stress corrosion cracking. Mechanically, Incoloy 800H has an elongation of 30–35%, a yield strength of about 275 MPa, and a tensile strength of about 600 MPa. At temperatures as high as 1100°F (593°C), the alloy retains its exceptional mechanical qualities and dimensional stability, which makes it appropriate for demanding thermal processing applications.

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 Industries that need strength at high temperatures and resistance to oxidation and carburisation frequently use forgings. In the petrochemical and chemical processing industries, they are perfect for parts of furnaces, pressure vessels, superheaters, reformer outlet manifolds, and heat exchangers. They are utilised in high-pressure boilers and steam generators in power plants. These forgings are also used in heat treatment equipment and nuclear power plants, where strength retention and thermal stability are crucial. They are a popular option for mission-critical components functioning in harsh thermal and corrosive conditions due to their superior weldability, creep resistance, and corrosion performance.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
