1) Remark: The material NiCr28FeSiCe with the material number 2.4889, also conained in the VdTÜV-Werkstoffblatt 519 : 2002-09, is applied in the form of strips, sheets, tubes and bars for furnace construction components. The material is an austenitic, creep-resistant nickel-chromium-iron alloy with a high chromium content and with controlled contents of silicium and rare earths. As a result of the formation of a well protecting external chromium oxide layer in combination with a silicium oxide layer located beneath it, the material is especially suitable for thermic refuse disposal plants. It is marked by excellent scale-resistance up to about 1000 °C, good high temperature tensile strength and creep strength depending on time, excellent resistance to oxidizing, reducing, nitriding and sulphur-bearing mediums in changing conditions, too, as well as by excellent properties in waste incineration gases at temperatures from 550 to 850 °C. Fields of application are environmental technology, coal-combusting and waste incineration plants, furnace construction and heat exchangers for industrial furnaces, as well as chemical and petrochemical processes in the range of elevated temperatures. A good resistance to gaseous mediums containing fluoride is given. The material is approved for pressure vessels (according to TRB 100) from -196 to +950 °C (>500 °C to 750 °C: limited). Processing properties: Formability: good Weldability: good
