ASTM B167 UNS N06600 Seamless Nickel Alloy Tube Inconel 600 Heat Exchanger Tube
ASTM B167 Inconel 600 / UNS N06600 Nickel Alloy Seamless Tube
Inconel 600's value comes from its excellent combination of properties:
-
High-Temperature Resistance: Excellent mechanical strength and resistance to oxidation (scaling) in air at temperatures up to 1175°C (2150°F).
-
Corrosion Resistance: Outstanding resistance to a wide range of corrosive environments, including:
-
Organic and inorganic acids
-
Chloride-induced stress corrosion cracking (better than many stainless steels)
-
Caustic environments (e.g., sodium hydroxide, making it a prime choice for caustic evaporators)
-
Water corrosion: Very resistant to pure and high-purity water.
-
-
Strength & Fabrication: Good mechanical properties over a wide temperature range and is readily formable and weldable using standard techniques.
-
Non-Magnetic: Remains non-magnetic from cryogenic temperatures up to its Curie point.

Why Choose Inconel 600?
You would select Inconel 600 when you need a proven, reliable alloy that offers an excellent balance of:
-
High-temperature strength and oxidation resistance.
-
Superior corrosion resistance, especially to caustics.
-
Ease of fabrication and welding.
It is a first-choice material for engineers dealing with aggressive thermal and chemical environments where standard stainless steels like 304 or 316 are insufficient.
