Product Details

Nickel 200 Plate, ASTM B160,astm b162, UNS N02201, Nickel 200 Wire


Nickel 200 and Nickel 201 are powerful solutions reinforced, commercially available pure wrought iron alloys. The nautical constraints of the metals have been united to one particular, dual-certified chemistry, leading to one lone metal with all the desirable faculties of the metals. When managing temperatures have been required to transcend 600°F, carbon material gets necessary. The decrease carbon material of Nickel 201 creates the content immune to graphitization and hence not as at the mercy of embrittlement. Strain vessels and parts might be assembled of Nickel 201 according to the ASME Boiler and Pressure Vessel Code, Section VIII, Division inch to set up to 1250°F.

Sectors & Purposes

Nickel 200/201 can be employed heavily from the compound and electronic equipment businesses. It's likewise used from the aerospace, petrochemical, electrical power production and marine/offshore technology businesses. Normal software whereby Nickel 200/201 can be used comprises electronic equipment and electroplating elements, caustic evaporators, gas ships, and food processing gear, caustic storage and handling gear, artificial fiber manufacturing, sodium creation as well as other procedures at which sodium hydroxide and fluorine are utilized.

Opposition to Corrosion

Nickel 200/201 presents exceptional corrosion immunity in lessening and impartial media in addition to in oxidizing atmospheres so long as the social media enables the creation of the nitric oxide picture. This oxide picture accounts because of it is metal's exemplary immunity to rust in caustic surroundings. This metal has seen usage within surroundings including alkalies and various usage within sulfuric, hydrochloric, anhydrous hydrofluoric along with non-aerated amino acids. Nickel 200/201 is immune to stress corrosion cracking in chloride salts and also to attack against non-oxidizing halides. Comfort and fever may impact this alloy's immunity in some specific surroundings.

Fabrication and Heat-treatment

All sexy cold and working methods might be properly used if forming Nickel 200/201. Hot-working temperatures ought to be between 1200°F and also 2250°F with significant forming to become executed at temperatures over 1600°F. Annealing ought to be done in a fever between 1300°F along with 1600°F. Care ought to be used when picking the anneal temperature as time-at-temperature to this might significantly affect the mechanical components and arrangement of this substance. Widespread Trade Names Nickel 200, Nickel 201

Alloy 200 is technically pure nickel with good mechanical properties and excellent resistance to alkali hydroxides as well as organic compositions. Even when exposed to high temperature. Alloy 200 retain its strength and is ductile at low temperature. Alloy 200 is a multipurpose grade and is used in application where alloys are not essential. It also has good magnetic and magnetostrictive properties, high thermal and electrical conductivity as well as low gas content in the electronics industry. Furthermore Alloy 200 is of interest for its good weld ability.

Available forms of Nickel 200 :

  • Sheet
  • Plate
  • Bar
  • Pipe & Tube (welded & seamless)
  • Fittings (i.e. flanges, slip-ons, blinds, weld-necks, lapjoints, long welding necks, socket welds, elbows, tees, stub-ends, returns, caps, crosses, reducers, and pipe nipples)
  • Wire

Corrosion Resistance Nickel 200

Nickel 200 and 20-1 plates have excellent immunity in most pollution environments such as hydrofluoric acid and alkalis. These metals work exceptionally well below diminishing conditions however might likewise be utilized in several states as a result of creation of the nitric oxide picture. The out standing immunity of impeccable 200 and 20-1 plates in caustics is dependant with such a safety.

In states in which temperatures transcend 600ºF (315ºC), Nickel 20-1 plates could be your favorite substance, as a result of the low carbon dioxide content.

The immunity of impeccable 200 and 20-1 plate at vitamin acid software changes based on the compression and fever, in addition to though the remedy will be aerated. The metals function better at non-aerated acidity remedies.

Nickel 200 and 20-1 plates work nicely in antioxidants, alkalis, along with impartial salt remedies. Nevertheless, in oxidizing salt answers, sturdy corrosion usually takes place.

Both metals withstand gases that are dry in room temperatures. Nickel 20-1 plates may be utilised in hydrogen ethanol and also sterile chlorine gasoline upward to 1022ºF (550ºC).
