Inconel 600 (UNS N06600) is a nickel-chromium alloy used for applications that need high temperature resistance and corrosion. This nickel alloy was developed for service temperatures from cryogenic to elevated temperatures in the range of 2000° F.
They have excellent mechanical properties, is non-magnetic and presents the desirable mix of high strength and good weldability under an array of temperatures.
The prime nickel content in Inconel 600 enables it to retain considerable resistance under reducing conditions, can make it resistant to corrosion by a number of organic and inorganic compounds, gives it excellent capacity chloride-ion stress-corrosion cracking plus offers excellent resistance to alkaline solutions.
The chemical composition of Inconel Alloy 600 is provided in the table below:

Properties of Inconel 600 (UNS N06600) are:
The mechanical properties are:
|Product Form||Condition||Tensile (ksi)||.2% Yield (ksi)||Elongation (%)||Hardness (HRB)|
|Rod & Bar||Cold-Drawn||80-100||25-50||35-55||65-85|
|Rod & Bar||Hot-Finished||80-100||30-50||35-55||65-85|
|Tube & Pipe||Hot-Finished||75-100||25-50||35*55||-|
|Tube & Pipe||Cold-Drawn||80-100||25-50||35-55||88 Max|
It is possible to both hot-form and cold-form alloy 600 using typical processes. Hot working must be performed between 1600° F and 2250° F avoiding any work between 1200-1600° F because the ductility decreases in this temperature range. Welding Alloy 600 can be achieved via shielded metal-arc welding, TIG, and MIG.
