Differences between Inconel 600 and Incoloy 825 sheet materials
Inconel 600 sheet is a high-nickel-content nickel-chromium alloy, thus exhibiting excellent high-temperature oxidation resistance. Incoloy 825 sheet is a nickel-iron-chromium alloy with added molybdenum, copper, and titanium, demonstrating superior corrosion resistance in a wider range of environments, particularly against acid corrosion and stress corrosion cracking. The main difference between the two lies in their composition, which leads to their performance differences: Inconel 600 sheet performs better at extremely high temperatures, while Incoloy 825 sheet offers better overall corrosion resistance at medium to low temperatures.
What is the difference between Inconel 600 and Incoloy 800h?
nconel is a nickel-chromium alloy, typically containing more than 50% nickel; while Incoloy is a nickel-iron-chromium alloy, containing less than 50% nickel. Incoloy 800 has a higher iron content and a lower nickel content, while Inconel 600 is cheaper.
Inconel 600 Plate
Inconel 600 plate is a nickel-chromium-chromium alloy renowned for its excellent high-temperature strength and oxidation resistance, maintaining structural stability at temperatures up to 2000°F (1093°C). Due to its high nickel content (≥72%) and high chromium content (14-17%), it resists chloride stress corrosion cracking and operates reliably in oxidizing environments. This plate is easy to cut, bend, and weld, and is widely used in furnace components, heat treatment fixtures, chemical equipment, and nuclear systems where high thermal stability and corrosion resistance are required.
Incoloy 825 Alloy Plate
Incoloy 825 alloy plate is a nickel-iron-chromium alloy with added molybdenum and copper, exhibiting excellent resistance to reduction, chloride, and sulfuric acid corrosion. Its balanced composition provides optimal corrosion resistance while maintaining good mechanical and machinability. It is ideally suited for harsh, corrosive environments and is commonly used in chemical processing, pollution control systems, acid production facilities, and marine applications where long-term durability and reliability are critical.
