Our seamless stainless steel and nickel alloy tubes and pipes are mainly used in the following industries:

Chemical and petrochemical industry

Power generation and Environmental technologies

Oil and gas applications

Mechanical and plant engineering and construction

Automotive industry

Seamless stainless steel tubes and pipes are the preferred choice for processes under the following conditions:

- high temperatures

- aggressive media (e.g. acid and lye)

- and/or high pressure

which call for the use of high-quality materials.

Incoloy 825 Corrosion resistance

825 is an all-purpose project alloy, have good corrosion resistance of the acid and alkali metal property in both oxidation and reduction environments. High nickel content made it with effective stress corrosion cracking resistance performance. 825 have excellent corrosion resistance in different kinds of media, such as sulfuric acid, phosphoric acid, nitric acid and organic acid, alkali metal such as sodium hydroxide, potassium hydroxide, and hydrochloric acid. A variety of media corrosion of nuclear-burning dissolver show 825 high integrated prpperty, like sulfuric acid, nitric acid and potassium hydroxide are all dealing in a same device.

Incoloy 825 Application field:

825 widely use in many kinds of industry field that the working temperature no more than 550°C.
