Mumbai, India-based Jyoti Steels is a prominent manufacturer and supplier of Incoloy 800/800H/800HT Flanges, which are renowned for providing high-quality components that can withstand high-temperature and corrosive applications. Offering precision, durability, and international standards compliance, Jyoti Steels offers flanges that provide superior structural stability and oxidation resistance. The flanges are suitable for challenging industrial uses such as petrochemical, thermal, and power generation industries. Supported by technical skills and customer satisfaction, Jyoti Steels supplies domestic as well as global markets with secure and efficient flange solutions.
Incoloy 800/800H/800HT Flanges are made up of Nickel (30–35%), Chromium (19–23%), Iron (39.5% min), supplemented by Aluminum (0.15–0.60%), Titanium (0.15–0.60%), and Carbon (0.05% max in 800; 0.05–0.10% in 800H/800HT). These flanges are very strong mechanically with a tensile strength of 520–590 MPa, yield strength of approximately 205 MPa, and elongation of about 30–35%. Physical properties are a density of 7.94 g/cm³ and a melting range of 1357°C to 1385°C. Due to their high thermal degradation, oxidation, and carburization resistance, they are very suitable for high temperature use.

Incoloy 800/800H/800HT Flanges are widely applied across petrochemical processing, power generation, nuclear power, and heat treatment facilities. They are best suited for high-temperature piping, heat exchangers, superheaters, and reactors because of their resistance to carburization, oxidation, and long-term thermal exposure. Their mechanical stability and corrosion resistance in temperatures over 1100°F (593°C) make them crucial in ensuring safe, leak-free connections in harsh service conditions. Moreover, their behavior in corrosive and oxidizing environments makes them an ideal choice for long-term industrial stability.
