Cold Drawn Nickel Alloy Steel Bar ASTM Standard N4 Nickel 201 Round Bar Corrosion Resistant
Pure nickel materials of different purity are mainly used in the fields of chemical industry, electroplating and electronics. Its corrosion resistance has good corrosion resistance in other reducing media except for its poor performance in alkaline media. Pure nickel has higher electrical conductivity, thermal conductivity and plasticity than nickel-based alloys. Pure nickel can be processed into products of different shapes.
N4 (Nickel 201, N02201) pure nickel alloy is a pure nickel alloy composed of trace elements such as manganese and copper and nickel. It has good mechanical properties and excellent resistance in many corrosive environments. Other useful features of the alloy include its magnetic properties, magnetostrictive properties, high thermal and electrical conductivity, low gas content and low evaporation pressure. The corrosion resistance of N4 makes it particularly useful in applications such as food, man-made fibers and caustic that require product purity. It is also widely used when corrosion resistance is a primary consideration in structural applications. Other uses include chemical drums, electrical and electronic components, aerospace, and missile components.

The main thoroughfare of N4 (Nickel 201, N02201) pure nickel alloy:
N4 (Nickel 201, N02201) pure nickel alloy is a solid solution alloy with a face-centered cubic structure. Typically, the microstructure exhibits a small amount of non-metallic inclusions, and the inclusions are mainly oxides and do not change with annealing. Nickel 201 is more commonly used when it is used above °F (315 °C). Nickel 200 and Nickel 201 are structural materials approved by ASME Boiler and Pressure Vessel Code. The N6 approved service temperature can reach 600°F (315°C) and the N4 approved service temperature can reach 1250°F (677°C).
