Mumbai, India-based Jyoti Steels is a leading manufacturer and supplier of superior-grade Incoloy 800/800H/800HT Tubing, intended for applications in corrosive and high-temperature environments. Established on the pillars of quality and customer satisfaction, Jyoti Steels offers tubing solutions of international quality and industry-specific standards. These tube products find broad applications in industries such as petrochemicals, power generation, and thermal processing with excellent mechanical strength, oxidation resistance, and metallurgical stability, even at very harsh thermal and pressure conditions.
Incoloy 800/800H/800HT Tubing consists of Nickel (30–35%), Chromium (19–23%), Iron (balance), and also Carbon (0.05–0.10% in 800HT), Aluminum (0.15–0.60%), and Titanium (0.15–0.60%). These alloys possess high mechanical strength with tensile strength of approximately 600 MPa, yield strength of approximately 275 MPa, and elongation of 30%. Physical properties are a density of 7.94 g/cm³ and a melting range of 1357°C to 1385°C. This composition provides the tubing with superior resistance to oxidation, carburization, and sulfidation and is thus ideal for continuous high-temperature service in hostile atmospheres.
