Abstract
The relative resistance of various materials and alloys to corrosion by laboratory slags was studied. The materials of interest were subjected to three selected laboratory slags: vanadium slag formed by mixing 70 percent V2O5 and 30 percent Na2SO4, non sulfated vanadium slag formed by mixing 79 percent V2O5 and 21 percent NaVO3, and a sulfate-chloride nonvanadium slag formed from 90 percent Na2SO4 and 10 percent NaCl. Materials showing greatest corrosion resistance to these slags were Hastelloy D, 100 Cr, 50 Cr-50Ni, and 25 Cr-5 Al-bal Fe. Other materials of greater utility showing good resistance were 60 Cr-40 Ni, 30 Cr-30 Ni-40 Co, 14 Cr-14 Mn-bal Fe, and Haynes-Stellite 31. 4.2.3
