m has been experimented within powder form exposed to a currentof nitrogen, the temperature being1,200 degs. C, without getting acombination. Vanadium is, appar-ently, the only possible rival at pres-ent. Even if it should be found tobe equal the present expense is com-paratively large. The cost of titan-ium is very moderate indeed. Fur-ther, the temperature required byvanadium for union with nitrogenappears to be a high one; whereastitanium unites with nitrogen at about800 degs. C. or less. Titanium is now obtainable in twoprincipal forms. In both, the princi-pal constituent is iron. Silicon, in apercentage ranging from 0.35 to 1.00,also occurs in both.

BENDING OF TITANIUM RAILS BY CRANE HOIST WITH RAIL UNDER PILE cent.; in the other it is less than Iper cent. The titanium percentage inboth ranges from 10 to 15. Thenon-carbon alloy is more expensive.It is used for special steels, and isunsuited for use with iron. The rea-son for the unsuitability with iron isprobably because of a higher melt- ing point of the non-carbon alloy.The mode of adding titanium alloyto the molten steel differs somewhatwith the mode of manufacture of thesteel itself. In general, the titaniumis the last thing added. It is not thepurpose that it should perform thewhole duty of deoxidizing. This is TITANIUM STEEL 491 more economically done with man-ganese and silicon alloys. The titan-ium performs the finishing work,eliminating impurities left behind bythe other purifiers. If the steel isbeing made by the acid open-hearthprocess and the manganese and sili-con are introduced while the moltenmetal is still in the furnace, the titan- ium alloy may be added during t
