UNS N07001 AMS 5544 Plate Nickel Alloys

Corrosion Resistance

Nickel Alloy plate possess excellent resistance in many corrosive environments including hydrofluoric acid and alkalis. These alloys perform extremely well under reducing conditions but can also be used in oxidizing conditions due to the formation of a passive oxide film. The outstanding resistance of Nickel Alloy plate in caustics is based on this type of protection. Pankh Steel is the top UNS N07001 AMS 5544 Plate Nickel Alloys Manufacturer in India

In conditions where temperatures exceed 600ºF (315ºC), Nickel 201 plate is the preferred material, due to its lower carbon content.

The resistance of Nickel Alloy plate in mineral acid applications varies depending on the concentration and temperature, as well as if the solution is aerated. The alloys perform better in non-aerated acid solutions.

Nickel Alloy plate perform well in acids, alkalis, and neutral salt solutions. However, in oxidizing salt solutions, strong corrosion can take place.

Both alloys resist dry gases at room temperatures. Nickel 201 plate can be used in hydrogen chloride and dry chlorine gas up to 1022ºF (550ºC)

Fabrication Data

Nickel Alloy plate can be easily welded and processed by standard shop fabrication practices.

• Hot Forming 

Hot bending operations should be performed in the temperature range of 1600º to 2250ºF (870º to 1230ºC). In any operation, care should be taken to avoid heating Nickel Alloy plate above the upper temperature limit of 2250ºF (1230ºC).

• Cold Forming

Nickel Alloy plate can be worked by any conventional cold-forming method. The forming characteristics are comparable to those of mild steel; however, because of the higher elastic limits of Nickel 200 and 201, greater power will be needed to perform the operations. Severe forming can be done manually but will require intermediate anneals to restore the alloy’s softness.

• Machining

Nickel Alloy plate should be machined in the annealed condition whenever possible. These grades have the propensity to work harden, making it necessary to utilize low cutting speeds and requiring the cutting tool to stay engaged at all times. An adequate chip depth is important in order to avoid contact with the previously formed work-hardened zone. Liquid cold forming lubricants should be utilized to assure optimal heat dissipation.

• Welding

Nickel Alloy plate can be joined by a variety of welding procedures including inert gas and resistance welding. Welding practices are similar to those used to join austenitic stainless steels. Neither preheating nor post-weld heat treatments are usually required.
