What is incoloy 825 material?

Incoloy 825, known as Nickel Alloy 825, is a nickel-iron-chromium alloy with small amounts of molybdenum, copper and titanium added. This combination makes Incoloy 825 more corrosion resistant in the harshest environments. Like many alloys in the Incoloy family, Incoloy 825 offers a number of benefits to the user:

Excellent corrosion resistance to reducing and oxidizing acids, such as sulfuric and phosphoric acids
Helps avoid stress corrosion cracking
Prevents localized corrosion, such as pitting and crevice corrosion
Extremely resistant to a wide range of oxidizing species, such as nitric acid, nitrates, and oxidized salts
Due to its superior corrosion resistance, Incoloy 825 is used in a wide range of industries and applications, including:

Chemical processing
Pollution control
Water heaters
Oil and gas recovery
Food, water, and seawater thermal containers
Acid production
Pickling tank heaters, tanks, and equipment
Nuclear fuel reprocessing
Radioactive waste disposal
Ship exhaust systems
Like most alloys in the Incoloy family, Incoloy 825 has a unique chemical composition, including:

Ni 38-46%
Fe 22% minimum
Chromium 19-23.5%
Molybdenum 2.5-3.5%
Copper 1.5-3%
Manganese 1% (max)
Titanium 0.6-1.2%
Gnee Steel offers Incoloy 825 alloy in various shapes and specifications including tubes, pipes, plates, strips, sheets, round bars, flat bars, forging billets, hexagons and wires. Incoloy 825 alloy in various specifications meets different key industrial standards set by organizations such as ASTM, ASME, BS, SEW, DIN, EN and ISO.
