Nickel Alloy 600 pipe, also known as Inconel® 600 pipe, is an extremely versatile nickel-chromium alloy capable of resisting oxidation in temperatures up to 2000 ºF (1093 ºC). It's also used in cryogenic environments, thanks to a minimum of 72% Nickel combined with chromium in its chemical composition. It exhibits corrosion resistance to both organic and inorganic compounds, as well as chloride-ion stress induced cracking. Nickel Alloy 600 is used in a variety of critical applications that require protection from corrosion and heat. It consists of 72% Nickel, 14-17% Cr, 6-10% Fe, 1% Mn, and 0.5% Si.

Alloy 600 Pipe is available in Seamless or Welded from Size ranges 1/8" up to 26". Listed below are common sizes. Please contact for sizes not listed.

N/A In nuclear power, reactor vessels and heat exchangers use Nickel Alloy 600 piping and tubing. For chemical processing, Nickel Alloy 600 parts resist most alkaline solutions, sulfuric compounds, and low rates of attack from chlorine and hydrogen chloride. In aerospace, gas turbine components and jet engines benefit from Nickel Alloy 600's properties. High temperature environments such as heat treatment furnace components and fixtures withstand corrosion thanks to its increased nickel content. It's readily fabricated using hot or cold treatments and can also be brazed, welded, and soldered using standard processes. We are a stocking distributor of all Inconel® 600 products including bar, rod, wire, forging stock, plate, sheet, strip, and tube forms.
