Introduction

ASTM B162 Pure Nickel Plate is the standard specification for commercially pure nickel plate, sheet, and strip, covering two primary grades: Nickel 200 (UNS N02200) and Nickel 201 (UNS N02201) . This commercially pure nickel plate contains a minimum of 99.6% nickel, delivering excellent corrosion resistance in caustic alkalis, outstanding thermal and electrical conductivity, and good mechanical properties across a wide temperature range. Nickel 200 plate is the standard grade for general corrosive service up to 600°F (315°C), offering high purity, excellent fabricability, and resistance to caustic soda and potash across wide concentration and temperature ranges. Nickel 201 sheet is the low‑carbon version (0.02% max C) of Nickel 200, specifically designed for elevated temperature service above 600°F where graphitization and embrittlement become concerns. Both grades are available in hot-rolled and cold-rolled forms, custom thickness (0.1mm–100mm), cut‑to‑size options, and supplied in annealed condition.

Specifications & Process Options

Applications

1. Chemical Processing & Caustic Alkali Industry

• In caustic soda evaporators, concentrators, and storage tanks handling sodium hydroxide (NaOH) and potassium hydroxide (KOH) across wide concentration ranges, ASTM B162 Nickel 200 plate delivers corrosion rates of less than 1 mpy in boiling 50% caustic soda. This alkali resistant nickel plate is the standard material for chlor‑alkali cell components and caustic handling equipment. Excellent resistance to caustic alkalis extends up to and including the molten state.

• For high‑temperature caustic service above 600°F, Nickel 201 sheet is preferred due to its low‑carbon composition, which prevents graphitization and maintains ductility in superheated caustic environments.

2. Electronics & Battery Industry

• For lithium‑ion and nickel‑metal hydride battery manufacturing, pure nickel strip for battery connections provides high electrical conductivity (approximately 70 W/m·K at 23°C) and excellent weldability. Nickel sheet for battery applications is used for battery connectors, tabs, and terminals essential for assembling NiMH, NiCd, and Li‑ion battery packs.

• For electronic components, semiconductor supports, and transistor enclosures, ASTM B162 nickel 200 sheet offers high purity and consistent electrical performance. Its high thermal and electrical conductivity makes it optimal for applications where heat transfer efficiency and electrical performance are critical.

3. Food Processing & Pharmaceutical Equipment

• For food processing equipment handling fatty acids, dairy products, and chemically sensitive foods, pure nickel plate preserves and houses chemically unsafe or perishable foods without contamination.

• For pharmaceutical manufacturing, ASTM B162 nickel sheet provides non‑toxic corrosion resistance in API synthesis equipment and clean‑in‑place systems, where product purity is critical.

4. Aerospace & Industrial Equipment

• For aircraft components, rocket motor cases, and missile components, Nickel 200 plate delivers reliable performance in moderately corrosive environments.

• For exhaust systems and heat‑generation devices, ASTM B162 pure nickel sheet withstands high temperatures and corrosive exhaust gases.

5. Heat Exchangers & Power Generation

• For heat exchangers and condensers in chemical and power generation facilities, high thermal conductivity nickel plate (79 W/m·K) provides efficient heat transfer with excellent corrosion resistance in aggressive cooling water and process streams.

FAQ – ASTM B162 Pure Nickel Plate

Q: What is the difference between Nickel 200 and Nickel 201?

A: Nickel 200 plate is the standard grade with 99.6% minimum nickel content, suitable for general corrosive service up to 600°F (315°C). Nickel 201 sheet is the low‑carbon version (0.02% max C) of Nickel 200, preferred for service above 600°F (315°C) to prevent graphitization and embrittlement by intergranular carbon. Nickel 201 also offers better intergranular corrosion resistance at elevated temperatures.

Q: Is pure nickel plate suitable for caustic alkali service?

A: Yes. ASTM B162 Nickel 200 plate provides outstanding resistance to caustic soda (NaOH) and caustic potash (KOH) across wide ranges of concentration and temperature. In boiling 50% sodium hydroxide, corrosion rates are less than 1 mpy. The alloy shows good resistance in acid, alkaline, and neutral salt solutions, and is particularly effective under reducing conditions. Nickel 201 plate is preferred for elevated temperature caustic service above 600°F.

Q: What industries commonly use ASTM B162 pure nickel plate?

A: Key industries include chemical processing (caustic evaporators, chlor‑alkali plants), electronics and battery manufacturing (battery connectors, terminals, semiconductor supports), food and pharmaceutical processing (processing equipment, storage drums), aerospace (aircraft components, rocket motor cases), and power generation (heat exchangers).

Q: What are the thermal and electrical properties of Nickel 200 plate?

A: Nickel 200 sheet offers high thermal conductivity of approximately 70–79 W/m·K at room temperature and electrical conductivity of about 18% IACS. These properties make it optimal for applications requiring heat transfer efficiency and electrical performance, such as heat exchangers, electrical connectors, and battery components.
