Product introduction
The editor
Cr content is usually 15-25% of the 800 alloy, nickel content is 30-45%, and contains a small amount of aluminum and titanium.
800 alloy from high temperature fast cooling after all in a single austenite zone, therefore, using a state as a single austenitic organization.
Alloy has the high chromium content and plenty of nickel content, so a higher resistance to high temperature corrosion performance, more in industrial application.
In the chloride, low concentration of NaOH aqueous solution and high temperature and high pressure water, has good resistance to stress corrosion cracking performance, so the equipment used in the manufacture of resistance to stress corrosion cracking
