The material 2.4675 is a nickel-chromium-molybdenum-copper alloy. This alloy is highly resistant to corrosion and is characterised by excellent resistance in oxidising and reducing media – even at high temperatures.
In addition, 2.4675 (Alloy C2000 ®) is highly resistant to pitting, crevice and stress corrosion cracking.
The material is also resistant to wet media such as sulphuric, phosphoric and nitric acid, chlorine gas, acid mixtures of sulphuric acid and oxidising acids with chloride ions.
2.4675 can also be used with strong oxidising agents such as iron (III) and copper (II) chlorides, chlorine, acetic acid and seawater.
