Hastelloy C-276 Manufacture Process
The manufacture of sheet is started with producing ingot by
advanced vacuum melting process. The sheet production includes
forging, rolling, annealing, acid-washing, polishing, etc. The
sheet is produced to the required sizes. From the ingot to the
final sheet, manufacture process is operated with high standard
quality control system. There will be quality test for each batch
of product, such as test to thickness tolerance, content, hardness,
HASTELLOY C276 is a Nickel-chromium-molybdenum wrought alloy that
is considered the most versatile corrosion resistant alloy
available. This alloy is resistant to the formation of grain
boundary precipitates in the weld heat-affected zone, thus making
it suitable for most chemical process applications in an as welded
condition. Alloy C-276 also has excellent resistance to pitting,
stress-corrosion cracking and oxidizing atmospheres up to 1900°F.

Some typical applications of HASTELLOY C276 include equipment
components in chemical and petrochemical organic chloride processes
and processes utilizing halide or acid catalysts. Other industry
applications are pulp and paper (digesters and bleach areas),
scrubbers and ducting for flue gas desulfurization, pharmaceutical
and food processing equipment.
HASTELLOY C-276 is a nickel-chromium-molybdenum alloy with
universal corrosion resistance unmatched by any other alloy. It has
outstanding resistance to a wide variety of chemical process
environments including ferric and cupric chlorides, hot
contaminated mineral acids, solvents, chlorine and chlorine
contaminated (both organic and inorganic), dry chlorine, formic and
acetic acids, acetic anhydride, sea water and brine solutions and
hypochlorite and chlorine dioxide solutions. Alloy C276 also
resists formation of grain boundary precipitates in the weld heat
affected zone making it useful for most chemical processes in the
as-welded condition. It has excellent resistance to pitting and
stress corrosion cracking.
HASTELLOY C276 sheet 0.044" thick in the heat-treated condition at
2050°F, rapid quenched, has an average olsen cup depth of 0.48".
Alloy C-276 can be successfully fabricated by many methods. The
alloy tends to work harden but with the proper care, the alloy is
readily hot and cold formed. Complete information on welding,
machining and forming is available
