Hi,

As per UHX 13.3; Yield strength shall be taken from TableY-1 in Section-II, Part D. When a yield strength value is not listed in TableY-1, one may be obtained by using the procedure in UG-28(c) (2) Step3.

If not possible then ask the manufacturer (which is selected by your client) to provide you the values.

Hope this will help.

Regards,
R.K.
