ASTM B423 UNS N08825 Nickel Alloy Seamless Pipe For Petrochemical Industry

ASTM B423 UNS N08825 refers to a seamless pipe manufactured from a nickel-iron-chromium alloy with additions of molybdenum, copper, and titanium (UNS N08825), produced in accordance with the ASTM B423 / ASME SB423 standard. This alloy is commonly known by the trademark Incoloy 825. This nickel alloy seamless pipe is designed for exceptional resistance to reducing and oxidizing acids, stress-corrosion cracking, and pitting, especially in aggressive environments like sulfuric and phosphoric acids. It’s available in a wide range of sizes, finishes, and delivery conditions, it serves critical roles in chemical, petrochemical, marine, and pollution control industries. YUHONG GROUP is professional in manufacturing nickel alloy pipes with 35 years’ experience. Our nickel alloy pipe can be seamless or welded. If you have demand of our pipes, just feel free to contact us.

Chemical Composition Table (ASTM B423 / UNS N08825):

Element	Weight % (min)	Weight % (max)
Nickel (Ni)	38.0	46.0
Chromium (Cr)	19.5	23.5
Iron (Fe)	22.0 (min)	Balance
Molybdenum (Mo)	2.5	3.5
Copper (Cu)	1.5	3.0
Titanium (Ti)	0.6	1.2
Carbon (C)	–	0.05
Manganese (Mn)	–	1.0
Silicon (Si)	–	0.5
Sulfur (S)	–	0.03
Phosphorus (P)	–	0.03
Aluminum (Al)	–	0.2

Key Advantages and Features:

Outstanding Corrosion Resistance
Resists Chloride Stress Corrosion Cracking
Pitting & Crevice Resistance
High Temperature Stability
Good Weldability
Excellent Fabricability
No Weld Seam Weakness

Different Surface Finish:

Finish Type	Description	Typical Application
Pickled (Pickled & Passivated)	Oxide scale removed by acid bath; passivated surface enhances corrosion resistance.	Standard for petrochemical service; ready for installation.
Bright Annealed	Annealed in controlled atmosphere; smooth, oxide-free, shiny surface.	High-purity applications, food / pharma, but also used for critical clean services.
Mechanically Polished	Abrasive finishing to certain Ra (e.g., 0.4μm, 0.8μm).	Internal surface for low friction or cleanability; sometimes used for sour gas lines to avoid deposit buildup.
Sand / Bead Blasted	Matte, uniform satin finish.	For aesthetic or coating preparation.

Different Applications:

Industry	Specific Uses
Chemical Processing	Heat exchangers, evaporators, reaction vessels, piping for sulfuric/phosphoric acid production
Oil & Gas	Sour service pipelines, downhole tubing, wellhead equipment, umbilicals
Pollution Control	Flue gas desulfurization scrubbers, stack liners, ducting
Marine / Offshore	Seawater cooling lines, firewater systems, ballast piping
Nuclear Power	Steam generator tubing, spent fuel reprocessing
Pharmaceutical / Food	Process lines requiring high purity and corrosion resistance to organic acids
Aerospace	Fuel and hydraulic lines exposed to corrosive fluids
