Inconel 600 is a nickel-chromium alloy designed for usage from cryogenic to elevated temperatures in the range of 2000oF (1093oC). The high nickel content of the alloy allows it to retain substantial resistance under reducing conditions and makes it resistant to corrosion by a number of organic and inorganic compounds. The nickel content gives it superb resistance to chloride-ion stress-corrosion cracking and also provides excellent resistance to alkaline solutions.
Its chromium content gives the alloy good 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, 600 has poor resistance. Alloy 600 is relatively un-attacked 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 outstanding mechanical properties and with a combination of high strength and good workability, it is readily weldable. Inconel 600 exhibits cold forming properties generally associated with chromium-nickel stainless steels
