ASTM B163 Incoloy NO2200 NO2201 NO4400 NO6600 Heat Exchanger Tube

ASTM B163 Incoloy NO2200 NO2201 NO4400 NO6600 Heat Exchanger Tube

ASTM B163 is a specification covering seamless nickel-iron-chromium alloy (also known as Incoloy) tubes for use in heat exchangers and other high temperature applications.

Terms such as NO2200, NO2201, NO4400, and NO6600 refer to specific alloy grades in the Incoloy family:

1. Alloy 200 (NO2200): This is a commercially pure wrought nickel alloy with good mechanical properties and excellent resistance to many corrosive environments, especially alkaline solutions.

2. Alloy 201 (NO2201): This is a low carbon version of Alloy 200 designed to reduce susceptibility to intergranular corrosion in welded applications. It has similar corrosion resistance, but better resistance to intergranular corrosion in the welded condition.

3. Alloy 800 (NO4400): This is a nickel-iron-chromium alloy used in high temperature applications where resistance to oxidation and carburization is required. It is widely used in chemical processing, nuclear energy, and cryogenic applications.

4. Alloy 600 (NO6600): This is a nickel-chromium alloy that has good mechanical properties and corrosion resistance over a wide range of temperatures and environments. It is commonly used in a variety of industries such as chemical processing, food processing, and power generation.

Each of these alloys has its own unique properties and can be selected based on the specific requirements of the application, such as high temperature resistance, corrosion resistance, and mechanical strength. When selecting materials according to ASTM B163, it is important to consider the specific environmental conditions and performance requirements of the intended use.
