About Alloy 400

Alloy 400 from NeoNickel has superb corrosion resistance, particularly in neutral and alkaline salts. It is also one of a limited number of alloys that can be used in conjunction with hydrofluoric acid and fluorine. With high nickel content, this alloy is immune to chloride-induced stress corrosion cracking. The alloy also has good mechanical properties from sub-zero temperatures up to 549°C.

This alloy also performs excellently in seawater, with improved resistance to cavitation corrosion compared with other copper-base alloys. It’s often used to handle sulphuric acid up to 80% concentration at room temperature and up to 15% sulphuric acid at boiling temperatures.
