Hastelloy C-4 - World Wide
Hastelloy C-4 is an alloy that is a nickel-chromium-molybdenum alloy
with outstanding high-temperature stability as evidenced by high
ductility and corrosion resistance even after aging in the 1200 to
1900F (649 to 1038C) range. This alloy is resistant against the
formation of grain-boundary precipitates in the weld heat-affected
zone, thus making it suit- able for most chemical process
applications in the as-welded condition. C-4 alloy also has
excellent resistance to stress-corrosion cracking and to oxidizing
atmospheres up to 1900F (1038C).
HASTELLOY C-4 alloy has outstanding resistance to wide variety of
chemical process environments. These include hot contaminated
mineral acids, solvents, chlorine and chlorine contaminated media
(organic and inorganic), dry chlorine, formic and acetic acids,
acetic anhydride, and seawater and brine solutions.
HASTELLOY C-4 alloy can be forged, hot-upset, and impact extruded.
Although the alloy tends to work-harden, it can be successfully
deep-drawn, spun, press formed or punched. All of the common methods
of welding can be used to weld HASTELLOY C-4 alloy, although the
oxy-acetylene and submerged arc processes are not recommended when
the fabricated item is intended for use in corrosion service.
Special precautions should be taken to avoid excessive heat input.
It is for theses reasons why industries trust Lightning Bolt for
their Hastelloy C-4 fasteners. This alloy can be made into nuts, hex
cap screws, hex bolts, stud bolts, nuts, washers, and a wide variety
of specialty fasteners. Contact Lightning Bolt to determine if
Hastelloy C4 fasteners would be a good fit for your corrosive
