Located in Hyderabad, India, Dhruv Metals is a renowned producer and supplier of high-grade Incoloy 800HT Forgings that are designed to perform exceptionally well in corrosive and high-temperature conditions. Dhruv Metals is renowned for their fine craftsmanship and commitment to global standards. They offer dependable forging solutions that are suited to the needs of the aerospace, power generation, petrochemical, and heat treatment industries. Because of its exceptional resistance to oxidation, carburisation, and heat stress, Incoloy 800HT is particularly prized. With a focus on customer satisfaction, product integrity, and on-time delivery, Dhruv Metals is a trusted partner for critical components in the most demanding operational settings.
Nickel (30–35%), chromium (19–23%), and iron (at least 39.5%) make up the majority of Incoloy 800HT Forgings, with titanium and aluminium (0.15–0.60%) added as well. Excellent resistance to high-temperature oxidation and structural deterioration is offered by this alloy. In terms of mechanical properties, Incoloy 800HT provides a tensile strength of roughly 600–750 MPa, a yield strength of roughly 300–450 MPa, and an elongation of 30–45%. Even after extended exposure to high temperatures, its exceptional creep and rupture strength is guaranteed by its stable austenitic structure. Its grain structure is improved by forging, which increases its mechanical dependability under high pressure and heat.

800HT Incoloy Applications requiring exceptional mechanical strength and resistance to oxidation at high temperatures frequently use forgings. In the chemical and petrochemical industries, they are crucial for heat exchangers, furnace parts, superheater tubes and reformer outlet manifolds. They are used in boiler parts and steam generators in the production of electricity. These forgings are used in components subjected to cyclic thermal stress in the nuclear and aerospace industries. Additionally, Incoloy 800HT is perfect for carburising settings like heat treatment fixtures and baskets. It is essential for high-pressure and mission-critical applications due to its stability, longevity, and high-temperature performance.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
