Known by its trade name, Inconel, or as UNS N06600, this nickel-chromium-iron solid solution strengthened alloy is ideal for use in a variety of applications. Its excellent corrosion resistance, high tensile and fatigue strength, good weldability and formability, and exceptional low-temperature properties make it an outstanding material for use in a range of harsh environments.
alloy 600 is resistant to both oxidizing and reducing compounds, mildly corrosive acids, and caustic alkalies. It also has good ductility in both the annealed and the normalized condition, which helps to ensure that parts made from this alloy will continue to function properly after being exposed to intense environmental stress. This is particularly important for industrial applications such as pollution control, waste processing, and vacuum and space equipment.
This nickel-chromium-iron alloy can be readily formed by conventional techniques, such as cold forming and hot forming. It is weldable by all standard methods, including TIG, MIG, and SMA welding. It is also readily machinable, although it is advised that major machining be conducted between 2300 and 1850 degF as its ductility declines in this range.
Inconel 600 has excellent low-temperature properties, and is able to maintain its toughness when used in applications that require resistance to cryogenic temperatures. This material is able to resist impact damage, as well as stress cracking due to the presence of a tough martensite microstructure. Stress-relieving is typically performed after hot working or forming to reduce residual stresses and prevent distortion.
