Nickel Alloy 601 and Inconel® 601 pipe is a general purpose alloy often used for a variety of engineering applications where resistance to heat and corrosion are vital. This nickel-chromium-iron alloy features an array of characteristics thanks to its high degree of metallurgical stability, good mechanical properties, and impressive creep rupture strength. It also exhibits good resistance to corrosion in aqueous environments. Consisting of 58-63% nickel, Nickel Alloy 601 includes a chemical content of 21-25% Cr, 1-1.7% Al, 1% Co, a balanced amount of Fe, a maximum of 1% Mn, 0.5% Si, 0.59% Si, and 0.015% S.

Alloy 601 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 While offering outstanding mechanical strength, Nickel Alloy 601 pipes are also easy to fabricate and machine using common methods. It can be welded and joined with conventional products and techniques. Thanks to its versatile set of properties, Nickel Alloy 601 is often used for a variety of major construction products. For heat treatment equipment, Nickel Alloy 601 and Inconel® 601 are used to produce baskets, trays, and fixtures. In the aerospace industry, igniters and diffuser assemblies in gas turbines utilize Nickel Alloy 601.

Power generation equipment is often manufactured using Nickel Alloy 601 to build tube supports, grid barriers, and ash-handling systems. With a combination of corrosion resistance and strength, Nickel Alloy 601 is often used for tubes, muffles, retorts, conveyor belts, chain curtains, and flame shields for industrial furnaces.
