ASTM B168 Basic Info

ASTM B168 serves as the definitive standard for the production of Nickel-Chromium-Iron Alloys (UNS N06600, N06601, N06603, N06690, N06693, N06025, and N06045) and Nickel-Chromium-Cobalt-Molybdenum Alloy (UNS N06617) sheets, plates, and strips. These alloys are renowned for their exceptional resistance to corrosion and oxidation in high-temperature environments, making them vital for applications in aerospace, chemical processing, and power generation.

Characteristics of ASTM B168

  • Versatility: The standard covers a range of nickel-chromium-iron and nickel-chromium-cobalt-molybdenum alloys, providing options for different requirements in terms of strength, corrosion resistance, and other properties.
  • Dimensional Accuracy: ASTM B168 sets strict requirements for the dimensions and tolerances of plates, sheets, and strips, ensuring consistency and compatibility in various manufacturing and construction applications.
  • Surface Finish: The standard specifies surface finish requirements, ensuring that the materials meet certain smoothness and appearance standards, which is crucial for applications where surface quality matters, such as in architectural uses or for components requiring tight seals.
  • Widely Accepted: ASTM B168 is an internationally recognized standard, widely accepted in industries where nickel-based alloys are used, providing a common language for manufacturers, suppliers, and users to ensure quality and consistency.

ASTM B168 Compare with Stainless Steel

Corrosion Resistance:

ASTM B168 Nickel Alloys: Offers excellent resistance to corrosion, especially in acidic and high-temperature environments.

Stainless Steel (e.g., 304, 316): While stainless steel is corrosion-resistant, it may not perform as well in highly corrosive or acidic environments compared to some nickel alloys.

Strength and Temperature Resistance:

ASTM B168 Nickel Alloys: Generally have high strength and excellent resistance to high temperatures.

Stainless Steel: Depending on the grade, stainless steel may have lower strength at high temperatures compared to nickel alloys.

Price Consideration:

ASTM B168 Nickel Alloys: Nickel alloys tend to be more expensive than stainless steel due to their unique properties and alloying elements.

Stainless Steel: Generally more cost-effective than nickel alloys, especially in common grades like 304 and 316.

Applications:

ASTM B168 Nickel Alloys: Preferred for applications where corrosion resistance and high-temperature performance are critical, such as chemical processing, aerospace components, and marine applications.

Stainless Steel: Widely used in various industries including construction, food processing, and medical equipment. It may be suitable for general-purpose applications with moderate corrosion requirements.

Machinability and Fabrication:

ASTM B168 Nickel Alloys: May require specialized machining tools due to their hardness. However, they can be formed and fabricated into complex shapes.

Stainless Steel: Generally easier to machine and fabricate compared to some nickel alloys. Stainless steel is known for its formability and weldability.
