Alloying steel having superior corrosion resistance to alkali metal oxides of salt melts containing

摘要

The present invention relates to a way with a high corrosion resistance with respect to hot salt melts, the chlorides and / or alkali metal oxides contain. The alloying steel is manufactured from a preparation which comprises: 20 to 40 w -% ni, 0 to 8 w -% cr, 0,05 w -% and less c, 0,5 w -% or less si, 1,0 w -% or less mn, 0,05 w -% or less s and the remainder, based on the total weight, fe. In the case of a low cr - content is the way of unusual corrosion resistance with respect to chloride and / or alkali metal oxide containing salt melts, including salt melts, which in the case of licl and li φ 2 φ o. Also shows the way of a stable corrosion resistance with respect to salt melts even at high temperature, but also in the case of a low temperature, and has superior machinability on. Thus, the way to form sheets, rods or tubes are processed, which for structural materials and structural components for the treatment of molten salts are used.
