CORROSION OF CHROMIUM-NICKEL STAINLESS STEEL IN LITHIUM (KORROZIYA NERZHAVEYUSHCHEI KHROMONIKELEVOI STALI V LITII)

Abstract

Three series of 1Kh18N9T stainless-steel specimens were tested for corrosion behavior in lithium at 700C for 10 or 200 hr. Series 1 and 2 specimens were tested in lithium containing a small amount of C14 isotope and in tanks made of 1Kh18N9T steel (series 1) or Armco-iron (series 2). In the case of series 3 specimens, the lithium contained 0.1% carbon in addition to C14 and the tanks were made of Armco-iron. The corrosion was found to follow the same pattern under all the conditions tested, and characterized by a gradual dissolution of chromium and nickel from the surface layer of the specimens. With decreasing chromium and nickel content the steel changes its structure and gradually loses its corrosion resistance.
