Nickel Alloy 600, Inconel 600


Nickel Alloy 600, also sold under the brand name Inconel 600.  It is a unique nickel-chromium alloy that is known for its oxidation resistance at higher temperatures. It is highly versatile and can be used in everything from cryogenics to applications that present elevated temperatures up to 2000°F (1093°C).  Its high nickel content, a minimum of Ni 72%, combined with its chromium content, provides users of Nickel Alloy 600 a number of benefits including:

  • Good oxidation resistance at high temperatures
  • Corrosion resistance to both organic and inorganic compounds
  • Resistance to chloride-ion stress corrosion cracking
  • Works well with most alkaline solutions and sulfur compounds
  • Lower rate of attack from chlorine or hydrogen chloride

Because of its versatility, and because it is the standard engineering material for applications which require resistance to corrosion and heat, a number of different critical industries use Nickel Alloy 600 in their applications. It is an superior choice for:

  • Nuclear reactor vessels and heat exchanger tubing
  • Chemical processing equipment
  • Heat treat furnace components and fixtures
  • Gas turbine components including jet engines
  • Electronic parts

Nickel Alloy 600 and Inconel® 600 are readily fabricated (hot or cold) and can be joined using standard welding, brazing, and soldering processes.  To be called Nickel Alloy 600 (Inconel® 600), an alloy must include the following chemical attributes:

  • Ni 72%
  • Cr 14-17%
  • Fe 6-10%
  • Mn 1%
  • Si .5%
