Product Description Alloy 201 shows good stability in corrosive media such as acids, alkalis and salts and is widely used in industrial elds such as petrochemicals, aerospace, power generation and marine engineering.Nickel201 Nickel Alloy Chemical Composition and PreparationThe chemical composition of Nickel201 nickel alloy is mainly composed of pure nickel (Ni) and trace impurities, in which iron (Fe), silicon (Si), copper (Cu), manganese (Mn), carbon (C) and other elements have low content.Precise proportioning and strict control of process parameters during preparation are crucial to the performance of the alloy.Nickel201 nickel alloy physical propertiesNickel201 nickel alloy has a high melting point (about 1455°C) and density (about 8.89 g/cm3), which makes it stable in hightemperature environments. Its coecient of linear expansion is approximately 13.3 x 10^-6/°C, exhibiting low thermal expansion, which is conducive to maintaining dimensional stability at high temperatures. High purity: Nickel201 is 99.6% pure and free of impurities and inclusions, ensuring its excellent physical and chemical properties. -Corrosion resistance:Nickel201 has excellent corrosion resistance in a variety of corrosive media such as acids, alkalis and salts, and has good stability for some strong acids and alkali solutions.- High-temperature strength: Nickel201 has excellent hightemperature strength, can maintain good mechanical properties in high-temperature environments, such as high-temperature alloys in the jet engine components.Ni201 steel pipe as a high-performance nickel-based alloy steel pipe, with its excellent corrosion resistance, high temperature stability and excellent mechanical properties, has demonstrated its irreplaceable role in a number of industrial elds. Whether in petrochemical, aerospace, power generation or marine engineering, Ni201 steel pipe provides a solid guarantee for the development of various industries with its reliable quality and performance. 1.

Packing*All of our nickel alloy seamless pipes and tubes are packaged according to international standards to prevent any possible damage or loss. By default, we will use thick woven plastic bags to bundle the finished pipes together in batches.For some special pipes and tubes that are vulnerable to dirt, scratches, stress, or rough handling, we will suggest using wooden cases for protection. Please note that wooden cases may incur extra costs not only for the case itself but also for increased freight costs, especially when using air transportation. To enhance customer experience, we also provide dedicated packaging according to your specific requirements."6.

Request quote on this grade. OverviewCommercially 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.CharacteristicsGood 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.ApplicationsManufacture 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.

The temperature range 1200°F to 2250°F is recommended and should be carefully abided as the proper temperature is the most important factor in achieving hot malleability. Full information of the forming process should be sought and understood before proceeding.Nickel 201 can be cold formed by all conventional methods, but because nickel alloys have greater stiffness than stainless steels more power is required to perform the operations.Nickel 201 is the low carbon version of Nickel 200. It is preferred to Nickel 200 for applications involving exposure to temperatures above 600°F. With low base hardness and lower work-hardening rate, it is particularly suited for cold forming.High Temperature Mechanical Properties of Annealed Nickel 201Temp.°FTensile Strength, PSIYield Strength, PSIElongation,%Reduction of Area, %Room58,50015,000507320056,10015,400457440054,00014,800447260052,50015,300427280041,20013,5005880100033,10012,1006084120022,20010,2007490 Nominal Mechanical Properties of Nickel 201FormConditionTensileYield StrengthElongationHardnessStrength(0.2% Offset)in 2" (%)KpsiKpsi Rod and BarHot Finished,50~6010-2540~6075~100 BrinellHot Finishedand AnnealedCold Drawn60~10035-9010~35125~200 BrinellCold Drawn50~6010-2540~6075~100 Brinelland AnnealedPlate 50~7012-2535~60---Hot RolledHot Rolled50~7012-3540~60---and AnnealedTube and pipe(Seamless)Cold Drawn50~7010-2840~6062 MaxAnnealedRockwell BStress Relieved60~10530-8515~3570~95Rockwell BStandardFormStandardMetal TypeUNS N02201BarASTM B160 Din 17752 BS 3076Wire SheetASTM B162 Din 17750 BS 3072PlateASTM B162 Din 17750 BS 3072FittingB366ForgingASTM B564 Din 17754Weld Wire Weld ElectrodeENi-1NA 12All formsDin2.4068Machinability RatingsMACHINING DATACarbide tools are suggestedfor rates better than 50% of Type 304.Machining TypeSuggested starting rates are:Single Point turning :Roughing - 0.15" depth, 0.015"/rev feed -175 SFMFinishing - 0.025" depth, 0.007"/rev feed - 200 SFMDrilling :1/4" Dia hole - 0.004"/rev feed - 60 SFM1/2" Dia hole - 0.007"/rev feed - 60 SFM3/4" Dia hole - 0.010"/rev feed - 60 SFMReaming :Feed - same as drilling - 100 SFMSide and Slot Milling :Roughing - 0.25" depth - 0.007"/tooth feed - 125SFMFinishing - 0.050" depth - 0.009"/tooth feed - 140SFMThese rates are for carbide tools,Type C-2 for roughing, drilling and reaming.Type C-3 for finishing.
