Alloy 600 (UNS N06600) is a versatile nickel-chromium-iron alloy that be utilized in temperatures ranging from cryogenic up to 2000°F (1093°C) and for corrosion resistant service. The high nickel content assures the alloy will be virtually immune to chloride-ion stress corrosion cracking while also providing corrosion resistance to many organic and inorganic compounds. The chromium content provides resistance to oxidizing environments at high temperatures or in corrosive media, it also resists sulfur compounds.
In high temperature service, Alloy 600 resists oxidation and scaling up to 2000°F (1093°C). It is well suited for applications requiring carburization resistance or in sulfur containing environments at moderate temperatures. However, it is subject to sulfidation at high temperatures.
Alloy 600 is non-magnetic and cannot be hardened by heat treatment, only by cold working. It can be easily welded and processed by standard shop fabrication practices.
