Heat-resistant alloys have high creep resistance and strength at high temperatures. They are used as the construction material for parts of internal combustion engines, steam and gas turbines, jet engines, furnaces, and atomic-power installations.
HIGH TEMPERATURE HEAT RESISTANT ALLOYS:
Inconel® 601 (UNS N06601) nickel-chromium-iron alloy is a general-purpose engineering material for applications that require resistance to heat and corrosion. The outstanding characteristic of Inconel® Alloy 601 is its resistance to high-temperature oxidation. The alloy also has good resistance to aqueous corrosion, has high mechanical strength, and is readily formed, machined, and welded.
Incoloy® Alloy 803 (UNS S35045) is an iron-nickel-chromium alloy. The nickel and chromium contents are higher than those of alloy 800H and 800HT. A cost-effective material that provides an exceptional level of high-temperature corrosion resistance in oxidation, sulfidation, and carburization environments.
Inconel® Alloy 600 (UNS N06600): A super alloy with endless industrial applications. Alloy 600 is an excellent choice for a variety of applications. It is a high-resistance material to corrosion and heat, and its high thermal conductivity means that it has a low thermal expansion coefficient. These properties make it suitable for use in a range of applications.
Alloy 625 Inconel® (UNS N06625) nickel-chromium alloy is used for its high-strength, excellent fabricability (including joining), and outstanding corrosion resistance. Service temperatures range from cryogenic to 1800°F. The strength of Inconel® Alloy 625 is derived from the stiffening effect of molybdenum and columbium on its nickel-chromium matrix; thus precipitation-hardening treatments are not required.
Incoloy® Alloy 800H/800HT (UNS NO8811). The alloy is typically used for applications involving long-term exposure to high temperatures where resistance is needed from oxidation, carburization, and other types of high-temperature corrosion. Hydrocarbon processing, heat-treat furnaces, and power generation are some of the most common applications where 800H & 800HT® are utilized.
