Nickel Alloy 825 Pipe, Tube, Plate & Bar Supplier | ASTM B423 B424 B425

INCOLOY® alloy 825 (UNS N08825 / W.Nr. 2.4858) is a nickel-iron-chromium alloy engineered for exceptional corrosion resistance in a wide range of demanding environments. The chemical composition of this nickel-based alloy, fortified with molybdenum, copper, and titanium, provides superior performance against reducing acids like sulfuric and phosphoric, as well as oxidizing media such as nitric acid. INCOLOY 825 offers proven resistance to chloride-induced stress-corrosion cracking, pitting, and crevice corrosion, while its titanium stabilization ensures immunity to intergranular attack. This combination of properties makes UNS N08825 a premier material for critical applications across chemical processing, pollution control, and offshore oil and gas industries.

Nickel Alloy 825 (UNS N08825), also widely known as Incoloy 825, is a corrosion-resistant nickel-iron-chromium alloy enhanced with molybdenum, copper, and titanium. The alloy is specifically engineered for aggressive industrial environments requiring outstanding resistance to oxidizing and reducing acids, chloride stress corrosion cracking, pitting corrosion, and crevice corrosion.

Compared with standard stainless steels, Nickel Alloy 825 pipe and tube products provide superior long-term stability in sulfuric acid, phosphoric acid, seawater, and mixed chemical processing systems. This makes the alloy highly preferred for offshore engineering, pollution control systems, heat exchangers, acid production equipment, and oil & gas processing facilities.

At Xi'an Dongmeng Group Co., Ltd, we manufacture and export a full range of Nickel Alloy 825 seamless pipes, welded tubes, plates, sheets, bars, rods, and forged fittings for global EPC contractors, industrial distributors, and OEM manufacturers.

Our products are widely exported to Europe, Southeast Asia, the Middle East, South America, and North America with strict compliance to ASTM, ASME, DIN, and EN standards.

Incoloy 825 (Nickel Alloy 825 or UNS N08825) is a nickel-iron-chromium alloy with additions of molybdenum, copper and titanium. It is high Nickel content material with minimum Ni 38% to 46%, combined with small value of Mo, Cu and Ti gives Incoly 825 enhanced corrosion resistance to many corrosive environments. It is similar to alloy 800 but has improved resistance to aqueous corrosion. Alloy 825 is especially resistant to sulfuric and phosphoric acids

Density 8.14 g/cm3, 0.294 lbs/in3, tensile Strength 586 Mpa (85 Ksi) minimum, yield strength 241 Mpa (35Ksi) minimum, It has excellent resistance to both reducing and oxidizing acids, to stress-corrosion cracking, and to locized attach such as pitting and crevice corrosion.

The higher comprehensive performance of Incoloy 825 is showed in nuclear combustion dissolvers with various corrosive media environment, such as sulfuric acid, nitric acid and sodium hydroxide mixed and processed in the same equipment.
