NIckel Alloy 201 Plate

Nickel 201 (UNS N02201), a member of the nickel-based alloy family, has an irreplaceable position in high temperature and harsh environments due to its unique properties. The reliable performance of this nickel-based alloy in extreme environments makes it a material link between traditional manufacturing and high-end equipment. HT PIPE is a ASTM B162 Alloy 201 plate supplier with 15+ export experience.

Chemical composition of Alloy 201 plate

The nickel content is not less than 99.0%. By controlling the carbon content below 0.02%, the risk of carbide precipitation in high temperature environments is effectively avoided. The precise ratio of trace components such as iron ( Less than or equal to 0.40%) and manganese ( Less than or equal to 0.35%) in auxiliary elements not only maintains the purity of the material, but also optimizes the processing performance.

Physical performance of Nickel alloy 201 plate

The alloy 201 has a density of 8.89 g/cm³, a melting point spanning the range of 1435-1446 degree , and excellent thermal stability. The unique combination of thermal conductivity of 62 W/(m·K) and resistivity of 0.096 μΩ·m makes it perform well in scenarios where heat transfer and electrical conductivity coexist.

mechanical performance of Nickel N02201 plate

The tensile strength in the annealed state is about 380 MPa, and the elongation can reach 40%. This balance of high strength and high plasticity gives the material good forming potential.

ASTM B162 Ni 201 Sheet Specification

Nickel 2.4068 Plate

Corrosion resistance of Ni N02201 sheet

First, in reducing media, its surface passivation film can effectively resist the erosion of strong acids such as hydrochloric acid and sulfuric acid. secondly, in the face of strong alkaline environments such as sodium hydroxide, it remains stable even when the concentration reaches 50% and the temperature rises to the boiling point, more importantly, in molten salt and dry halogen media, its corrosion resistance far exceeds that of ordinary stainless steel.

Cold rolling of Alloy N02201 sheet

During cold processing, it is recommended to control the deformation amount of each pass within 15%, and the intermediate annealing temperature is preferably 700-850 degree .

welded of nickel 2.4068 plate

Tungsten inert gas welding (GTAW) is preferred for welding, and the purity of the shielding gas must reach 99.998%. Rapid cooling after welding can avoid excessive grain growth.

Heat treatment of alloy 2.4061 plate

Annealing treatment should be kept in the range of 760-925 degree and then quenched in water. When the treatment temperature exceeds 540 degree , the sulfur content in the furnace should be controlled below 50ppm to prevent sulfur embrittlement.
