Inconel 600 Sheet - AMS 5540 - UNS N06600 Alloy
Inconel® 600 (AMS 5540) is a high-performance nickel-chromium alloy built to withstand the toughest environments. Engineered for use from cryogenic conditions up to 2000°F (1093°C), it delivers strength, reliability, and durability where other materials may fail. The alloy’s high nickel content offers exceptional resistance to reducing environments and chloride stress corrosion cracking, while chromium provides added protection against oxidation and scaling at high temperatures.
With excellent mechanical properties and the ability to be hardened through cold working, Alloy 600 is trusted in industries where safety, longevity, and performance are critical. From chemical processing and heat treating to aerospace, nuclear, and electrical, this alloy has a proven track record of reliability.
At United Performance Metals, we supply Inconel® 600 in sheet and coil, available in a variety of stock sizes to meet your production needs. Whether you need materials that can handle corrosive chemicals, extreme heat, or demanding mechanical stress, Alloy 600 delivers consistent performance you can count on.

Characteristics of Inconel 600
Nickel Alloy 600 (UNS N06600) is highly valued for its ability to perform in harsh environments where other alloys fall short. Unlike Alloy 200, Alloy 600 offers superior resistance when exposed to sulfur compounds and strongly oxidizing conditions. It is virtually immune to chloride ion stress corrosion cracking, making it an excellent choice for applications involving saltwater or corrosive chemicals. In caustic alkali environments, stress relieving at elevated temperatures (1650°F / 900°C for 1 hour) prior to service is recommended for optimal performance.
Working with Inconel 600
Machining Alloy 600 requires careful handling due to its tendency to work harden. It is best machined in the annealed condition using heavy-duty tooling, with performance comparable to stainless steel 304. The alloy can also be cold formed using standard fabrication methods, offering flexibility in manufacturing. Non-magnetic and tough, Alloy 600 exhibits forming characteristics similar to chromium-nickel stainless steels.
Alloy 600 can be joined using conventional welding, brazing, and soldering techniques without the need for post-weld annealing. This makes fabrication simpler and more efficient, while still ensuring long-lasting performance in demanding environments.
