In any process system, it is much more cost
effective to pro-actively design for corrosion
control than to re-actively make repairs
because of design deficiencies. Until now,
sanitary process system designers have
been limited to 300 series stainless steels
and AL-6XN® alloy for sanitary tubing and fit-
tings. Central States Industrial has respond-
ed to the need for a more corrosion resistant
alloy in sanitary process systems. In part-
nership with Haynes International
Incorporated, CSI has developed a stocking
program of Hastelloy® C-22® sanitary tubing
and fittings; the superior alloy for many cor-
rosion-plagued processes.
The corrosion resistance of any metal is only
as good as its design limitations. For
instance, austenitic 300 series stainless
steels perform exceptionally well in many
standard food, beverage, and pharmaceutical
environments. However, in applications
where chlorides are introduced to the
process, upgrading to "super austenitic"
grades such as AL-6XN alloy may
be necessary.
Although AL-6XN alloy solves sev-
eral corrosion issues plaguing
processors' systems, it is not the
answer to all corrosion
problems. Any alloy
will fail when used
in applications
beyond its design
limitations. In indus-
tries such as chemical, bio-technology,
and pharmaceutical processing, both
oxidizing and reducing acids, or chlorides
and high process temperatures may be pres-
ent. In these applications it is advantageous
to use a nickel-based alloy such as Hastelloy
C-22 due to its resistance to localized corro-
sion in these applications.
1
Hastelloy C-22 alloy is the most versatile
nickel-chromium-molybdenum-tungsten alloy
available today. With improved resistance to
both uniform and localized corrosion, it will
out-perform C-276, C-4 alloys, and alloy 625
in a variety of mixed industrial chemicals.

The Hastelloy C-22 alloy has outstanding resistance to pitting, crevice corrosion and stress corrosion
cracking. It has excellent resistance to oxidizing aqueous media including wet chlorine and mixtures
containing nitric acid or oxidizing acids with chloride ions. Hastelloy C-22 also offers optimum resist-
ance to environments where reducing and oxidizing conditions are encountered in process streams.
Because of such versatility, it can be used where “upset” conditions are likely to occur, or in multi-
purpose plants.
Hastelloy C-22 alloy has exceptional resistance to a wide
variety of chemical process environments. Some of these
include strong oxidizers such a ferric and cupric chlorides,
chlorine, hot contaminated solutions (organic and inorgan-
ic), formic and acetic acids, acetic anhyride, and seawater and
brine solutions.
To clarify, oxidation is the adding of or combining with oxygen. This term is
sometimes extended to include combining with some other element of negative valence, such as
chlorine. Reduction is the taking away of oxygen or a negative valence.
Hastelloy C-22 alloy resists the formation of grain-boundary precipitates in the heat-affected zone
making it suitable for most chemical process applications in the as-welded condition.

Heat TreatmentWrought forms of Hastelloy C-22 alloy are fur-
nished in the solution heat-treated condition.
Additionally, after severe cold forming such as
elbow bending or tee pulling, CSI performs a
complete solution anneal at 2050° F, followed
by an argon quench to eliminate any residual
stress put into the part during fabrication.
