We could produce Hastelloy C-4 plate and sheets with Sizes
range from 4.5MM thick to 200MM thickness, up to 3000 wide.
The thickness of Hastelloy C-4 strips and coil that we could do
range from 0.05MM to 3MM
The surface finish of Hastelloy C-4 strips and coils that we could
do is as follows:2B / 2D / BA
The hardness of EN Hastelloy C-4 strip and coils that we could do
is as follows:1/4 Hard, 1/2 Hard, 3/4 Hard, Full Hard, Spring Hard,
Annealed, Pickled Soft
Customers can select a number of processing options to produce
Hastelloy C-4 plate to their exact specifications, reducing
materiel costs, production time, scrap and internal handling. All
stainless steel grades of plate can be cut
We can polish nearly any Hastelloy C-4 plates,sheets,coils,strips
to a #4 polish, #6 Polish, #7 polish or a #8 mirror finish. Our
Hastelloy C-4 plate,sheets,coils,strips can be polished on one side
or two sides.
In order to control the quality of Hastelloy C-4
plate,sheets,coils,strips,Test pieces are cut from each
plate,sheets,coils,strips and sent to our Metallurgical Laboratory,
where, aided by a computerized Certificate of Test system, experts
determine if the plate,sheets,coils,strips meet all requirements
for shipment. Each plate,sheets,coils,strips is analyzed on an
optical emission spectrometer to verify chemical content. The
microstructure of the plate,sheets,coils,strips is examined for
strength, ductility, and corrosion resistance. All additional scrap
is separated by grade and returned to a melt shop for recycling

Features: Hastelloy C-4 has outstanding high-temperature stability, and has
excellent resistance to stress-corrosion cracking and oxidizing
atmospheres up to 1040°C. It has exceptional resistance to a wide
variety of chemical process environments, including hot
contaminated mineral acids, solvents, chlorine and chlorine
contaminated media (organic and inorganic), formic and acetic
acids, acetic anhydride, and seawater and brine solutions.
Applications: Chemical processing involving wet chlorine, hypochloric acid,
hydrochloric acid, acetic acid and acetic anhydride; flue gas
scrubber systems; pickling operations; and electro-galvanizing.
