4. Mechanical properties
Table 2 summarizes the tensile and hardness characteristics of selected materials. The influence of sampling direction is particularly important for yield strength and elongation at break.
For thin pilger tubes used in nuclear applications (thickness around 0.5 mm), the Kearns factors are approximately f L = 0.06, f T = 0.34, f N = 0.60. For thicker products (e.g. extruded tube, hot-rolled sheet with a thickness of 6 mm), the transverse factor f T may be significantly higher, to the detriment of f N (f T = 0.50, f ...

Norms and standards
Most standards for zirconium and hafnium metal products, or alloys, are American ASTM standards. A few French standards also exist. Few standards concern hafnium.
