What are Inconel 825 Pipes & Tubes?

Inconel 825 Pipes & Tubes (UNS N08825 / Incoloy® 825) are vital components made from a nickel-iron-chromium superalloy containing additions of molybdenum (Mo), copper (Cu), and titanium (Ti). This composition provides outstanding resistance to a wide array of corrosive media, both reducing and oxidizing.

Key characteristics include:

• High Nickel Content (38-46%): Resists chloride-ion stress corrosion cracking (SCC).
• Chromium (19.5-23.5%): Offers resistance to oxidizing agents like nitric acid.
• Molybdenum (2.5-3.5%): Enhances resistance to pitting and crevice corrosion.
• Copper (1.5-3.0%): Improves resistance to reducing acids like sulfuric and phosphoric acid.
• Titanium (0.6-1.2%): Allows for stabilization heat treatment, preventing sensitization and intergranular corrosion after welding or heat exposure.

Inconel 825 Alloy Pipes and UNS N08825 Tubes are solid-solution strengthened, offering good fabricability and weldability. They maintain useful mechanical properties from cryogenic temperatures up to about 1000°F (540°C), above which performance may degrade. They provide a reliable solution for handling aggressive chemicals, sour gas, and acidic environments where standard materials fail.

Chemical Composition and Mechanical Properties

The performance of Inconel 825 Pipes & Tubes is defined by its controlled chemistry and resulting mechanical strength.

Chemical Composition (Typical %)

Element	Symbol	Min	Max	Role
Nickel	Ni	38.0	46.0	Base, SCC & general corrosion resistance
Chromium	Cr	19.5	23.5	Oxidizing resistance
Iron	Fe	22.0	Bal.	Base element
Molybdenum	Mo	2.5	3.5	Pitting/crevice & reducing acid resistance
Copper	Cu	1.5	3.0	Sulfuric/phosphoric acid resistance
Titanium	Ti	0.6	1.2	Stabilization against sensitization
Carbon	C	-	0.05	Controlled low
Manganese	Mn	-	1.0	Deoxidizer, hot workability
Sulfur	S	-	0.03	Kept low
Silicon	Si	-	0.5	Deoxidizer
Aluminum	Al	-	0.2	Minor element

Mechanical Properties (Annealed Condition)

Property	Typical Value	Units (Imp/Metric)	Notes
Tensile Strength	85 - 120 ksi	586 - 827 MPa	Min 85 ksi / 586 MPa often required
Yield Strength (0.2%)	35 - 65 ksi	241 - 448 MPa	Min 35 ksi / 241 MPa often required
Elongation in 2"	30 - 50 %	%	Good ductility (Min 30% common)
Hardness	70 - 90 HRB	Rockwell B	Typical range

Temperature Limit: Useful strength up to approx. 1000°F (540°C). Not typically strengthened by heat treatment (solid solution alloy). Cold work increases strength but reduces ductility.
