800 alloys typically contain 15 to 25 percent Cr, 30 to 45 percent nickel, and small amounts of aluminum and titanium. After high temperature and fast cooling, all 800 alloys are in austenite single zone. Therefore, the service state is single austenite structure. The alloy has high chromium content and sufficient nickel content, so it has high high temperature corrosion resistance.
In chloride, low concentration NaOH solution and high temperature and high pressure water, it has excellent stress corrosion cracking resistance, so it is used for manufacturing stress corrosion cracking resistance equipment.
