ASTM B160 UNS N02201 Nickel Round Bar Diameter 4 - 200mm HR CR Nickel 201 Alloy

Products Specification

Introduce of Nickel 201 / UNS N02201

Nickel 201 alloy is a commercially pure wrought alloy having properties similar to that of nickel 200 alloy, but with a lower carbon content to avoid embrittlement by inter-granular carbon at high temperatures.

It is resistant to acids and alkalis, and dry gases at room temperature. It is also resistant to mineral acids depending on the temperature and concentration of the solution.

Characteristics of Nickel 201

• 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.
