ATI 600™ alloy (UNS Designation N06600) is a nickel-chromium alloy designed for use from cryogenic to elevated temperatures in the range of 2000°F (1093°C). ATI 600™ alloy is non-magnetic and readily weldable.

The alloy is used in a variety of corrosion resistant applications. The high nickel content of the alloy provides a level of resistance to reducing environments, while the chromium content of the material provides resistance to weaker oxidizing environments. The high nickel content of the material provides exceptional resistance to chloride stress corrosion cracking.

The forming properties of the ATI 600™ alloy are similar to those of stable austenitic stainless steels.
