R u n a w a y corrosion b y f l u o r i n e now c h e c k e d by M o n e l a n d Inconel e v e n at high temperatures Chemical and petroleum processors handle fluorine today with compara tive ease and safety. Even at pressures as high as 800 psi. or at temperatures well over 1000 ° F , spontaneous ignition by elemental fluorine and the "slow burn" of corrosion by its compounds is being held in check. High nickel alloys provide check rein
Monel* nickel-copper and Inco nel* nickel-chromium alloys, it has been found, resist attack by fluorine over a -wider range of pressures and temperatures than other commonly used construction materials. In addition, they have excellent physical properties and are easily worked and welded. / \

At moderate temperatures . . . in aqueous systems . . . Monel is used
U p to about 900 °F, Monel alloy shows good resistance to fluorine. It also resists liquid fluorine, hydro fluoric acid, anhydrous H F , H F steam mixtures and active fluorides. Currently, Monel alloy is widely used in nuclear fuel separation and H F alkylation processes .. · for fluo rine generation cells, heat exchang ers, scrubbers, process piping, con trol instruments and other equip ment. When temperatures go up...Inconel
Inconel alloy also provides high resistance to fluorine and other cor rosives plus outstanding resistance to heat and thermal shock. A typical
pressures use is in the furnaces where anhy drous H F is reacted with uranium oxide to produce uranium tetrafluoride.
