Strip/Foil: 0.02mm-16mm

Pipe: 6mm*0.5mm-1200mm*100mm

Bar: Ф6mm – Ф600mm

Nickel 200 is commercially pure wrought nickel combining useful strength and ductility with high thermal and electrical conductivity. It is selected for many alkaline and reducing environments, especially where equipment must preserve product purity. The material is readily formed and welded. For prolonged exposure above approximately 315°C, low carbon Nickel 201 is generally preferred because Nickel 200 can suffer graphitization related embrittlement.

Product specifications

Product form Specification route Qualification
Plate sheet strip ASTM B162 / ASME SB162 Rolled products
Rod bar ASTM B160 / ASME SB160 Wrought solid products
Seamless pipe tube ASTM B161 / ASME SB161 General seamless products
Heat exchanger tube ASTM B163 / ASME SB163 Seamless condenser and heat exchanger tube
Welded pipe ASTM B725 / ASME SB725 Welded pipe
Welded tube ASTM B730 / ASME SB730 Welded tube
Wire ISO 9724; DIN 17753 Manufacturer referenced specifications

Product standards are grade specific. ASME counterparts require the edition adopted by the relevant construction code. [6, 13]

Mechanical properties

Product and condition Tensile MPa Yield MPa Elongation %
Annealed rod bar 380–520 105–210 40–55
Annealed hot rolled plate 380–550 105–275 40–60
Annealed sheet 380–520 105–210 40–55
Annealed tubing 380–520 85–210 40–60

Nominal room temperature ranges; yield is 0.2 percent offset and elongation uses approximately 51 mm gauge length. These are not specification minima. [6]

Application areas

  • Caustic chemical handling and processing equipment
  • Food and synthetic fiber processing equipment
  • Electrical connectors and electronic components
