ASME B31.3 K304.1.2 - HIGH PRESSURE PIPING "S" VALUE

[vi_shj]

Hi,

I need to design high pressure piping as per ASME B31.3 section K304.1.2 with API 5L X60 pipe.
When i checked for "S" value in Table K-1 under 300 deg F temperature it doesn't have any value. Which value should i consider for it. please advise

It is in ASME B31.3-2018.

Thanks jmec. Also please explain where i can see the allowable stress value for inconel 625 pipe in table K-1. It is not listed even in 2018 edition

Allowable stresses for unlisted materials may be determined per K302.3.2 c.
