Since 1999, Central States Industrial (CSI) has
proactively responded to the demand for more
corrosion resistant alloys in the high-purity and
sanitary markets by stocking tubing and fittings in
both AL-6XN® and Hastelloy® C-22®.
Al-6XN and C-22 are widely used in the biotech,
pharmaceutical, personal care, home care, food, dairy,
and beverage industries. These alloys are recognized
by the ASME BPE standard, which identifies several
specifications in Part MM (Metallic Materials) and by
the U.S. Food and Drug Administration (FDA).
Microbial contamination, system reengineering,
maintenance downtime, production loss, and safety
of employees and the environment are the main
reasons why end-users, architects, and engineers
select Super Alloys™.
When process media become aggressive,
the oxide film on system components breaks
down, resulting in corrosion. Finding the proper
metal with a compatible chemical composition
leads to a stable oxide film that resists media-specific
corrosion.
The main types of corrosion aecting hygienic
and high purity applications in aggressive chloride
environments are pitting, crevice, and stress
corrosion. Materials with a high composition of
chromium, nickel, molybdenum, and nitrogen provide
stronger resistance to these types of corrosion.
In chloride-induced solutions with high temperatures
and low pH values, AL-6XN is a better option than
300 series alloys such as 316L/1.4404 and 1.4435 for
more aggressive environments, a nickel-based alloy
such as Hastelloy C-22 is a more resistant alternative.
When process equipment breaks down, it is vital
to determine the cause of failure to prevent future
replacement and production losses. For example, if a
piping system made from 316L fails in an aqueous salt
environment with high temperatures, a Super Alloy
with a higher molybdenum content can be a solution
for the life of the system.
