Alloy 600

CMI Alloy Data Sheet
Description:
Alloy 600 is a nickel-chromium alloy designed for use from cryogenic to elevated temperatures
in the range of 2000 degF(1093 degC). The high nickel content of the alloy enables it to
retain considerable resistance under reducing conditions and makes it resistant to corrosion
by a number of organic and inorganic compounds. The nickel content gives it excellent
resistance to chloride-ion stress-corrosion cracking and also provides excellent resistance
to alkaline solutions. Its chromium content gives the alloy resistance to sulfur compounds
and various oxidizing environments. The chromium content of the alloy makes it superior to
commercially pure nickel under oxidizing conditions. In strong oxidizing solutions like hot,
concentrated nitric acid, it has poor resistance. Alloy 600 is relatively unattacked by the
majority of neutral and alkaline salt solutions and is used in some caustic environments.
The alloy resists steam and mixtures of steam, air and carbon dioxide. Alloy 600 is
non-magnetic, has excellent mechanical properties and a combination of high strength and
good workability and is readily weldable. Alloy 600 exhibits cold forming characteristics
normally associated with chromium-nickel stainless steels. Typical corrosion applications
include titanium dioxide production (chloride route), perchlorethylene syntheses, vinyl
chloride monomer (VCM), and magnesium chloride. Alloy 600 is used in chemical and food
processing, heat treating, phenol condensers, soap manufacture, vegetable and fatty acid
vessels and many more. Corrosion Materials specializes in the supply of pipe, fittings,
flanges and bar from stock. Material is stocked from 1/2" through 8" diameter and can be
supplied in random lengths, cut to order or machined to specifications. Machining includes
drilling, turning, tapping, threading, CNC shapes, flanges and others.
