This is an unretouched photograph of chloride-ion stresscorrosion cracking. The alloy shown has good resistance to general corrosion by chlorides. However, in the presence
of chlorides at stresses as low as 2000 psi and temperatures as low as 140 °F., it has a tendency to crack. INCOLOY alloy 800 resists this type of stress-corrosion cracking.
Problem: Chloride-ion stress-corrosion cracking Solution : I N C O L O Y A L L O Y 8 0 0 INCOLOY* alloy 800 was developed for use as a high t e m p e r a t u r e material. But, processors find it an increasingly effective and economical answer to the problem of chloride-ion stress-corrosion cracking in heat exchanger tubing. INCOLOY alloy 800 resists chlorideion s t r e s s - c o r r o s i o n c r a c k i n g even under conditions of alternate w e t t i n g
(at a surprisingly low cost, too)
and drying a n d / o r vapor phase exposure. An austenitic, nickel-chromiumiron alloy, INCOLOY alloy 800 resists a wide range of corrosives...retains its s t r e n g t h at high t e m p e r a t u r e s . If you're having heat exchanger tubing problems caused by chlorides in river or industrial cooling waters, specify t u b i n g of INCOLOY alloy 800.
