INCONEL 600

Technical Information for Nickel 600

Nickel 600 (UNS N06600) is a standard engineering material for applications which require resistance to corrosion and heat. The alloy also has excellent mechanical properties and presents the desirable combination of high strength and good workability.

The high nickel content gives the alloy resistance to corrosion by many organic and inorganic compounds and also makes it virtually immune to chloride-ion stress-corrosion cracking. Chromium confers resistance to sulfur compounds and also provides resistance to oxidizing conditions at high temperatures or in corrosive solutions.

Nickel 600 is not precipitation hardenable; it is hardened and strengthened only by cold work. The versatility of Nickel 600 has led to its use in a variety of applications involving temperatures from cryogenic to above 2000°F (1095°C).

Mechanical Properties of Nickel 600

In the annealed condition, Nickel 600 exhibits moderate yield strengths of 25,000 to 50,000 psi (172 to 345 MPa). Yield strengths in that range, combined with elongations of 55 to 35%, permit the alloy to be fabricated with little difficulty. Heavily coldworked material, however, can have tensile strengths as high as 220,000 psi (1517 MPa).

Corrosion Resistance

The high nickel content of Nickel alloy 600 provides good resistance to moderate levels of reducing conditions. The nickel content of the alloy renders the alloy extremely resistant to chloride stress corrosion cracking. Nickel alloy 600 is used in solutions of magnesium chloride. Similarly, the chromium content of Nickel 600 provides resistance to weak oxidizing environments. In this respect, Nickel alloy 600 is an improvement over Nickel 200 (commercially pure nickel). In strong oxidizing solutions like hot, concentrated nitric acid, the alloy has poor resistance.
