Fajar Metals, a leading manufacturer and supplier based in Jakarta, Indonesia, specializes in high-performance Incoloy 800/800H/800HT Tubing, designed to withstand tough thermal and corrosive environments. These nickel-iron-chromium alloy tubes are crafted to resist oxidation, carburization, and high-temperature scaling, all while ensuring outstanding structural integrity. With improved carbon levels and carefully controlled additions of aluminum and titanium in the 800H and 800HT grades, this tubing boasts exceptional creep and rupture resistance. Fajar Metals provides these tubes in accordance with ASTM B407/B514 standards, available in various sizes and finishes, making them perfect for critical applications in heat exchangers, furnace components, and chemical processing systems.
Incoloy 800/800H/800HT Tubing generally contains Nickel (30–35%), Chromium (19–23%), and Iron (the balance), along with trace amounts of Aluminum (0.15–0.60%), Titanium (0.15–0.60%), and Carbon (up to 0.10%). The mechanical characteristics include a tensile strength ranging from 500–600 MPa, yield strength exceeding 200 MPa, and elongation of up to 45%. The 800H and 800HT versions are particularly noted for their enhanced creep-rupture properties, making this tubing ideal for high-temperature applications. These alloys also offer excellent dimensional stability, corrosion resistance, and thermal fatigue endurance, especially during extended use at elevated temperatures.
