254SMO is a SANDVIK product with UNS number UNS S31254. . Once you know the UNS number look up Table 1A stress table in ASME Sec II part D. Looks like this material was added in 2015 code version. Allowable stresses for this material are based on product form and thickness. So, you will need to have all details before looking up the table. Your answers are in this table.

Please see in Table A-1 / A-1M at 20Cr–18Ni–6Mo
Please note that tensile values are not the same for thk. >3⁄16 and ≤3⁄16
Please consider Basic Quality Factor acc. to Table A-1B for the relevant pipe description.
