"Our magnesium chloride heat exchangers operate at 50 psi. and average temperatures of 180° F.," said a producer of magnesium. "The air-free solution is circulated at a vetocitv of 61/2feet a second. Our present equipment suffers from corrosion pitting and stress corrosion cracking." I N C O Technical Service reviewed a l l reports o n m a g nesium chloride which w e r e contained in the Corrosion D a t a File. A comprehensive summary of this information w a s sent to the producer. ( H e l a t e r requested a d d i t i o n a l copies f o r members of h i s staff.) Space limitations make it impossible to g i v e complete details of t h e summary h e r e . * The principal conclusions drawn w e r e : 1 Corrosion rate o f Inconel i n relatively air-free solutions of hot magnesium chloride will o r d i n a r i l y b e less t h a n I mdd2 Inconel is usually not subject t o pitting b e l o w t h e l i q u i d level. 3
Inconel is not subject to stress corrosion cracking.
