Product Description
ASTM B163 UNS N08825 DIN 2.4858 Incoloy 825 Nickel Alloy Heat Exchanger Tube Designated as UNS N08825 or DIN W.Nr. 2.4858, Incoloy 825 (also known as "Alloy 825") is an iron-nickel-chromium alloy with additions of molybdenum, cooper and titanium. The molybdenum addition improves its resistance to pitting corrosion in aqueous corrosion application while copper content bestows resistance to sulfuric acid. Titanium is added for stabilization. The Alloy 825 has excellent resistance to both reducing and oxidizing acids, to stress-corrosion cracking, and to localized attack such as pitting and crevice corrosion. It is especially resistant to sulfuric and phosphoric acids. Incoloy 825 alloy is mainly used for chemical processing, petrochemical piping, pollution-control equipment, oil and gas well piping, nuclear fuel reprocessing, acid production, and pickling equipment.
Corrosion Resistance
The outstanding property of Incoloy 825 is its corrosion resistance. In reducing & oxidising conditions, Incoloy 825 resists general corrosion, pitting & crevice corrosion, intergranular corrosion and stress corrosion cracking. It is particularly useful in sulphuric & phosphoric acids, sulphur containing flue gases, sour gas and oil wells and sea water.
Fabrication
Incoloy 825 can be readily hot or cold worked. Hot working should be in the range 870 - 1180°C, finishing at 870 - 980°C. For maximum corrosion resistance hot worked parts should be stabilise annealed before use. The alloy is easier to cold form than stainless steels.
Heat Treatment
Incoloy 825 is stabilise annealed at 940°C. The softest structure is obtained at 980°C. Sections heavier than sheet, strip and wire should be quenched to avoid sensitisation.
Incoloy 825 is one of the most effective alloy choice for severe environments. Its usefulness in varying climate, especially with regards to general and local corrosion makes the Incoloy WERKSTOFF NR. 2.4858 Pipe in industries such as - chemical processing, pickling operations, pollution control, acid production, nuclear fuel reprocessing, as well as the handling of radioactive wastes. According to most Incoloy 825 Seamless Pipe manufacturer, the industry that reaps the benefits of this alloy is the oil and gas industry, where they are useful in the recovery, extraction and conveyance of media across.

By default, we will use thick woven plastic bags to bundle the finished pipes together in batches. For some special pipes and tubes that are vulnerable to dirt, scratches, stress, or rough handling, we will suggest using wooden cases for protection. Please note that wooden cases may incur extra costs not only for the case itself but also for increased freight costs, especially when using air transportation. To enhance customer experience, we also provide dedicated packaging according to your specific requirements." | |
