Probably the material isn't permitted by the code. The specification is for sanitary tube, not pressure pipe, and you shouldn't be using it for installations covered by piping codes. You'll find allowables for it in the specification itself, unless there's no minimum mechanicals required. Typically the yield and ultimate strengths are 30 ksi and 70 ksi respectively.

Don't even think about using non-ASME specified materials in piping code applications, and don't even pretend to use the piping code with the stuff just because someone you never met guessed at the mechanical properties on a mailing list.
