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.
