Hastelloy

Fasteners likewise
has magnificent resistance to oxidizing
aqueous media, consisting of wet chlorine and
mixtures containing nitric acid or
oxidizing acids with chlorine ions. Hastelloy
C-22 Fasteners have tolerance to
oxidizing acid chlorides, wet chlorine, formic
and acetic acids, ferric and cupric
chlorides, salt water, brine, and other natural
and inorganic mixed or polluted
chemical solutions. Such nickel alloys give
optimal protection against circumstances
where process streams undergo reducing and
oxidizing conditions. Hastelloy Alloy C22
Fasteners resist the development of grain-limit
accelerates in the weld
heat-influenced area, subsequently making it
suitable for most chemical process
applications in the as-welded condition. Alloy
C22 Fasteners ought not to be
utilized as a part of service temperatures above
1250 degrees F because of the
formation of adverse stages which form over this
temperature.
Hastelloy C22 Fasteners have advantageous
characteristic features like
resistance to pitting, crevice corrosion and
stress corrosion cracking, exceptional
resistance to both decreasing and oxidizing
media, outstanding tolerance to
oxidizing aqueous media, exceptional resistance
to a wide range of chemical process
environments including strong oxidizers such as
ferric acids, acetic anhydride and
seawater, and brine solutions, Resists the
formation of grain-boundary precipitates
in the weld heat-affected zone, excellent
weldability.
