Material Standard - NORSOK Standard "Y03"

[kander]

We are taking delivery of a number of high pressure caps with a material NORSOK Y03.

Anyone have any idea what this material relates to in real money?

Norsok is a Norweigen Petroleom Materials standard.

The following link should give you more info.

Tough question as NORSOK appeared to have made a little error with their latest version of M-120: Y03 is referenced in the intro text but there is no datasheet.

Assume it is one of the 355 grades from EN 10025.

Your right SJones. (Thanks to piping designer & yourself)

I have found a Rev 2 of M-120 which states Y03 having:

NORSOK Grade = S355J2G3 / EN 10025 for plate & sections
&
NORSOK Grade = S355N1 / prEN 10225 for Tubulars

Why it is missing from M-120 Rev 4 is one of lifes little mysteries.
