Neil Metals, based in Kolkata, India, stands out as a top manufacturer and supplier of high-quality Incoloy 800H Forgings, designed to excel in high-temperature environments while resisting corrosion. Renowned for their precision, reliability, and durability, our Incoloy 800H Forgings are crafted using cutting-edge forging techniques and rigorous quality checks. These forgings are perfect for tough industrial settings like petrochemical processing, power generation, and heat-treating equipment. With a strong focus on customer satisfaction, Neil Metals provides tailored sizes and shapes to fit specific needs, ensuring consistent quality and prompt service, making us a go-to source for high-performance Incoloy 800H products.
Incoloy 800H Forgings mainly consist of iron (the balance), nickel (30–35%), and chromium (19–23%), along with small amounts of aluminum, titanium, and carbon. This unique blend offers remarkable resistance to oxidation, carburization, and high-temperature corrosion. Compared to Incoloy 800, Incoloy 800H boasts enhanced creep and rupture strength, particularly at temperatures exceeding 600°C (1112°F). The alloy showcases impressive tensile strength (typically 85–95 ksi), solid yield strength, and excellent metallurgical stability even under extended thermal exposure. These characteristics make Incoloy 800H Forgings ideal for pressure vessels, high-heat components, and critical structural applications in corrosive and thermally cycling environments.
