Hastelloy˘ C-2000

Hastelloy C2000a

Hastelloy C-2000 Bars is a nickel-chromium-molybdenum alloy that can be used in extremely corrosive environments. It offers superior resistance to pitting, crevice corrosion and stress corrosion cracking compared to other alloys, such as stainless steel and copper. It maintains good mechanical properties even at high temperatures, making it an ideal choice for processors or chemical plants working with highly corrosive acids and alkalis. ASTM B574 UNS N06200 Round Bar are often used in the aerospace, food processing, nuclear energy, petrochemical and medical industries because they resist oxidation over long periods without losing strength or shape. The alloy is also known for its exceptional formability when it comes to welding applications as well as its impressive dimensional stability during heat treatments.

 Hastelloy˘ C-2000 Chemical Resistance

Besides being resistant to acids, HASTELLOY® C-2000® alloy strip also stands up to process streams that contain traces of ferric ions and dissolved oxygen. Furthermore, it is exceptionally resistant to chloride solutions that can lead to stress corrosion cracking, something that is common among stainless steels. It can also withstand pitting and crevice attack when it comes in contact with chlorides. Perhaps its greatest strength is that it is still as easy to weld and to form as other Nickel alloys on the market.
