Hot Rolled Incoloy 825 Aloy 825 UNS N08825 W.Nr.2.4858 NS142 NA16 Plate Sheet Coil Strip Manufacturer in China

Incoloy 825 Sheet was brought to the market in 1952, building upon Incoloy 800 in order to better resist sulphuric acid. Copper additions are well-known to improve resistance to reducing environments, such as sulphuric acid. This property of Incoloy 825 Sheet is also exploited in Ferralium 255 (containing 2% copper additions) and the much more highly alloyed Alloy 20 (3-4% copper) to great effect. Although the nickel content is lower than the likes of Inconel 625 and Inconel 718, UNS N08825 plate is still sufficient to impart resistance to stress corrosion cracking (SCC) in chloride-containing environments. The increased chromium content of W.Nr.2.4858 plate ensures good resistance to oxidising environments such as nitric acid, whilst the molybdenum additions are well-known to improve pitting corrosion resistance.

The mechanical properties of Incoloy 825 Sheet is relatively constant from very low temperatures (considered cryogenic i.e. -150degC) up to 540degC (100degF). Above this temperature there is the possibility of undesirable microstructural phase changes that significantly reduce impact toughness and elongation.
