UNS N08810 alloy steel plate, also known as Incoloy 800, is supplied by Gangsteel, a leading stainless steel supplier in China. Renowned for its excellent UNS N08810 oxidation resistance and carburization resistance at high temperatures up to 1100°C (2012°F), this nickel-iron-chromium alloy is ideal for furnace components, petrochemical processing, and power generation.
Gangsteel offers UNS N08810 plate, sheet, bar, and custom components, meeting ASTM B409 and ASME SB-409 standards. This page provides detailed insights into the UNS N08810 chemical composition, mechanical properties, equivalent materials, specifications, applications, and competitive UNS N08810 price per kg. Explore our nickel alloy steel grades for related alloys like UNS N06625, UNS N08811, and UNS N08020.
UNS N08810is a nickel-iron-chromium alloy with approximately 30-35% nickel, 19-23% chromium, and balance iron, designed for high-temperature strength and resistance to oxidation and carburization. Its controlled carbon content and grain size make UNS N08810 material ideal for furnace tubes, heat exchangers, and petrochemical equipment. Compared to UNS N08811, UNS N08810 offers similar performance but is optimized for lower temperature ranges with better creep resistance.
Gangsteel’s UNS N08810 alloy steel plate is tailored for high-temperature industrial applications, providing a robust alternative to nickel alloy steel grades like UNS N06690 and UNS N08028.
