ASTM B474
Hastelloy® C-22
· UNS Number N06022
· Other common names: Alloy C22
This specification covers electric fusion welded pipe suitable for
high-temperature or corrosive service. The pipes are designated
into five classes namely Class 1, Class 2, Class 3, Class 4 and
Class 5, according to how they are to be welded. The joints shall
be full penetration double-welded or single-welded butt joints
employing fusion welding processes. The furnished pipe shall
undergo heat treatment and a chemical analysis shall be employed
for both plate and weld. Each pipe shall be subjected to transverse
tension test, transverse guided weld bend test and hydrostatic
pressure test.
Hastelloy C22, also known as alloy C22, is a versatile austenitic
nickel-chromium-molybdenum-tungsten alloy with enhanced resistance
to pitting, crevice corrosion and stress corrosion cracking. The
high chromium content provides good resistance to oxidizing media
while the molybdenum and tungsten content give good resistance to
reducing media. This nickel steel alloy also has excellent
resistance to oxidizing aqueous media including wet chlorine and
mixtures containing nitric acid or oxidizing acids with chlorine
ions. Other corrosives Hastelloy C-22 has resistance to are
oxidizing acid chlorides, wet chlorine, formic and acetic acids,
ferric and cupric chlorides, sea water, brine and many mixed or
contaminated chemical solutions, both organic and inorganic. This
nickel alloy also offers optimum resistance to environments where
reducing and oxidizing conditions are encountered in process
streams. This is beneficial in multi- purpose plants where such
“upset” conditions occur frequently.
This nickel alloy resists the formation of grain-boundary
precipitates in the weld heat-affected zone, thus making it
suitable for most chemical process applications in the as-welded
condition.

Fabrication of Hastelloy C-22
Although ductile enough to be formed by cold working, intermediate
annealing may be necessary due to work hardening. Forging should be
performed between 1750-2050° F followed by rapid cooling. Annealing
can be performed at a temperature range between 2020-2150° F
followed by a rapid quench. Cooling at an accelerated rate avoids
the formation of detrimental phases which form between 1400-1800°
F. Welding can be done by gas tungsten-arc, gas metal-arc and
shielded metal-arc processes.

6.Hot-Rolling Steel
Hot rolling is a mill process which involves rolling the steel at a
high temperature (typically at a temperature
over 1700° F), which is above the steel’s recrystallization
temperature. When steel is above the
recrystallization temperature, it can be shaped and formed easily,
and the steel can be made in much larger
sizes. Hot rolled steel is typically cheaper than cold rolled steel
due to the fact that it is often manufactured
without any delays in the process, and therefore the reheating of
the steel is not required (as it is with cold
rolled). When the steel cools off it will shrink slightly thus
giving less control on the size and shape of the
finished product when compared to cold rolled.
Uses: Hot rolled products like hot rolled steel
bars are used in the welding and construction trades to make
railroad tracks and I-beams, for example. Hot rolled steel is used
in situations where precise shapes and
tolerances are not required.
