Chinese wholesale Nickel Alloy Wire - Hastelloy C BAR/ Sheet/Pipe/ Bolt – Sekonic

Common Trade Names: Hastelloy C、NS3303、UNS N10002、W.Nr. 2.4819

HastelloyC alloy is a versatile Ni-Cr-Molybdenum-Tungsten alloy that offers better overall corrosion resistance than other existing Ni-Cr-Molybdenum-Hastelloy C276,C4 and 625 alloys.
Hastelloy C alloys have excellent resistance to pitting, crevice corrosion and stress corrosion cracking.
It has excellent resistance to oxidizing water media, including wet chlorine, nitric acid or a mixture of oxidizing acids containing chloride ions.
At the same time, Hastelloy C alloys also have the ideal ability to resist the reducing and oxidizing environments encountered during the process.
With this versatility, it can be used in some troublesome environments, or in factories for a variety of production purposes.
Hastelloy C alloy has exceptional resistance to various chemical environments, including strong oxidizing substances, such as ferric chloride, copper chloride, chlorine, thermal pollution solution (organic or inorganic), formic acid, acetic acid, acetic anhydride, seawater and salt solution.
Hastelloy C alloy has the ability to resist grain boundary precipitation formation in the welding heat affected zone, which makes it suitable for many kinds of chemical process applications in the welding state.
