WPS for P8-1 Material

[UKCats]

I recently ordered a custom made 316L SS vessel. The WPS they sent me for approval is for 304L SS base material. Since both 304L and 316L materials are a P8 Group 1 materials, I think this WPS is okay???

Anybody know???

Yes, except if additional supplementary requirements like, chemistry, corrosion and/or ferrite number specified.....

If it moves, train it...if it doesn't move, calibrate it...if it isn't written down, it never happened!

Yes indeed, one more situation to add, if you have overlay in flanges then also you may have to have wps of 316L
