TITANIUM

(Chemical Symbol Ti) – Element No. 22 of the periodic system; atomic weight 47.90; melting point about 3270?F.; boiling point over 5430?F.; specific gravity 4.5. Bright white metal, very malleable and ductile when exceedingly pure. Its principal functions as an alloy in the making of steel (1) Fixes carbon in inert particles (a) reduces martensitic hardness and hardenability in medium chromium steel (b) prevents formation of austenite in high-chromium steels (c) prevents localized depletion of chromium in stainless steel during long heating. Now finding application in its own right because of its high strength and good corrosion resistance.
