INCOLOY 890

没有此类产品
产品描述
INCOLOY® alloy 890 (UNS N08890) is the latest addition to the INCOLOY alloy family of heat-resistant alloys. Alloy 890 joins existing INCOLOY products in offering high strength along with excellent resistance to oxidation, carburization and sulfidation at temperatures up to 2200°F (1200°C). Alloy 890 offers the high chromium content of alloy 803 along with enhanced properties from additions of molybdenum, silicon and niobium. The primary application for alloy 890 is tubes for ethylene pyrolysis furnaces.
