ASTM B162 - Nickel 200 / Nickel 201 Plate, Sheet, and Strip
ASTM B162 describes standards for Nickel 200 and Nickel 201 in plate, sheet, and strip form. These commercially pure nickel alloys are known for their exceptional corrosion resistance, good ductility, and good mechanical properties even in harsh environments, such as those at higher temperature.
Nickel 201 is a low carbon alloy, containing 0.02% maximum carbon, designed to be used in environments above 600°F (315°C) to prevent intergranular embrittlement. The alloys possess exceptional corrosion resistance in reducing environments, in neutral environments, in alkaline solutions, and in salt solutions.
Properties of ASTM B162 Nickel Alloys
- Corrosion Resistance: Excellent in caustic soda, acids, and seawater environments.
- Thermal Stability: Nickel 201 is approved for service up to 1250°F (677°C).
- Formability: Easily fabricated through spinning, cold forming, or welding.
- Mechanical Integrity: Maintains ductility and strength under thermal cycling.
- Low Carbon Advantage: Prevents graphite precipitation and carbon embrittlement at high temperatures.
