Commercially pure wrought Nickel with similar properties to Alloy 200 but with a lower carbon content to prevent embrittlement by inter-granular carbon at elevated temperatures.
Characteristics
Good resistance to corrosion in acids and alkalis and is most useful under reducing conditions.
Outstanding resistance to caustic alkalis up to and including the molten state.
In acid, alkaline and neutral salt solutions the material shows good resistance, but in oxidising salt solutions severe attack will occur.
Resistant to all dry gases at room temperature and in dry chlorine and hydrogen chloride may be used in temperatures up to 550C.
Resistance to mineral acids varies according to temperature and concentration and whether the solution is aerated or not. Corrosion resistance is better in de-aerated acid.
Virtually immune to inter granular attack above 315C, chlorates must be kept to a minimum.
Applications
Manufacture and handling of sodium hydroxide, particularly at temperature above 300C.
Production of viscose rayon. Manufacture of soap.
Analine hydrochloride production and in the chlorination of aliphatic hydrocarbons such as benzene, methane and ethane.
Manufacture of vinyl chloride monomer.
Reactors and vessels in which fluorine is generated and reacted with hydrocarbons.
