Chung Metal provides Incoloy 800, 800H, and 800HT Bars and Rods—nickel-iron-chromium alloys that are intended for strength and oxidation resistance at high temperatures. These grades are specifically designed for applications in heat exchangers, industrial furnaces, and petrochemical equipment. 800H and 800HT are variants of 800, which have been improved to provide greater creep and rupture strength. Our bars are made to meet ASTM B408 and other international specifications, guaranteeing consistent performance under high pressure and temperature conditions. Made in Da Nang, they are relied upon by industries requiring performance in thermal and corrosive environments.
Incoloy 800 series alloys usually contain 30–35% nickel, 19–23% chromium, and iron as balance. 800H/HT have more carbon (~0.05–0.10%) and controlled aluminum + titanium for enhanced high-temperature strength. Tensile strength is 550–675 MPa, yield strength is about 200–350 MPa, with elongation of ~30–45%. These alloys are resistant to oxidation, carburization, and sulfidation in high-heat conditions. Density is ~7.94 g/cm³. They have good stress rupture properties and metallurgical stability at 600–1100°C.
