ASTM B163 Tubes Mechanical Properties
ASTM B163 is a standard specification for seamless nickel and nickel alloy condenser and heat exchanger tubes. The tubes are specifically designed to withstand high temperatures and pressure while providing excellent corrosion resistance. These properties make them ideal for use in various industrial applications, including chemical and petrochemical processing, power generation, and seawater desalination.

ARockwell or equivalent hardness values apply only to the annealed ends of stress-relieved tubing. Caution should be observed in using the Rockwell test on thin material, as the results may be affected by the thickness of specimen. For thickness under 0.050 in. (1.27 mm) the use of the Rockwell superficial or the Vickers hardness test is suggested. For hardness conversions for nickel and high-nickel alloys see Hardness Conversion Tables E 140.
