Inconel® Alloy 601

Common Trade Names: Inconel 601; Alloy 601; Nickel 601; Pyromet 601; Nicrofer 601;
Nickelvac 601; Ferrochronin 601.

INCONEL® alloy 601 (UNS N06601/W.Nr. 2.4851) is a general-purpose engineering material for applications that require resistance to heat and corrosion. An outstanding characteristic of INCONEL® alloy 601 is its resistance to high- temperature oxidation. The alloy also has good resistance to aqueous corrosion, has high mechanical strength, and is readily formed, machined and welded. The alloy's nickel base, in conjunction with substantial chromium content, provides resistance to many corrosive media and high- temperature environments. Oxidation resistance is further enhanced by the aluminum content.

The properties of INCONEL® alloy 601 make it a material of broad utility in such fields as thermal processing, chemical processing, pollution control, aerospace, and power generation.

Available Product Forms: 

Pipe, tube, sheet, strip, plate, round bar, flat bar, forging stock, hexagon and wire.
