    摘要: A metallic tube for heating a medium or subject outside thereof or inside it by transfer of heat energy through walls of the tube, in which heat is absorbed or emitted at least to a substantial degree by radiation on one or both of the inner and outer surfaces of the tube, is of a material forming a layer of essentially AI2O3 on the surfaces thereof when heated to at least approximately 75O0C. At least one of the external and the internal surface of the tube is coated by one of a metal, metal alloy and metal compound, which after oxidation forms a layer having an emissivity coefficient exceeding 0.7, or by a layer essentially consisting of a metal oxide which has an emissivity coefficient exceeding 0.7.

    摘要: A method of producing an FeCrAl material by gas atomisation, wherein in addition to containing iron (Fe), chromium (Cr) and aluminium (Al) the material also contains minor fractions of one or more of the materials molybdenum (Mo), hafnium (Hf), zirconium (Zr), yttrium (Y), nitrogen (N), carbon (C) and oxygen (O). The invention is characterised by causing the smelt to be atomised to contain 0.05-0.50 percent by weight tantalum (Ta) and, at the same time, less than 0.10 percent by weight titanium (Ti). According to one highly preferred embodiment, nitrogen gas (N2) is used as an atomising gas to which a given amount of oxygen gas (O2) is added, said amount of oxygen gas being such as to cause the atomised powder to contain 0.02-0.10 percent by weight oxygen (0) at the same time as the nitrogen content of the powder is 0.01-0.06 percent by weight. The invention also relates to a high temperature material.
