Mechanical Properties:

1)Average value from three tests; only one individual value may fall short of the specified minimum value by not more than 30%

2)For cold finished tubes in the NBK condition(annealed above the upper transformation point under shielding gas or in a vacuum), minimum values of yield stress lower than these values by 20N/mm2 are permitted.

3)For cold finished tubes in the NBK condition, minimum values of tensile strength lower than these values by 10n/mm2 are permitted.
