How is Tensile Strength Established by Tube Spec?

I'm working with an unlisted B31.3 material for a tubing spec. I want to determine the allowable stress for the flexibility analysis.

I've obtained the ASTM standards that are applicable. The base ASTM spec (A 270) does not specify a tensile strength. The General Requirements (A 1016) does not specify a tensile strength. The spec calls for UNS S31603. I understand UNS to be a numbering practice, and that it would not spec the tensile requirements.

How is the tensile strength established by these specifications?
