Confusion about Norm specifications... 1

[cbrn]

Hi,
I'm facing a bit of confusion about two European Norms regarding constructional steels:
- EN 10025-2: regards laminated products. Which is the currently released version of this Norm? The steel S355J2G3 seems to have been retired from the 10025: is it really so? Which is NOW the correct denomination for the "S355-type" material with resilience refered to -20°C? I seem to know that S355ML and S355NL are fine-grain "sub-types" so they shouldn't be considered as equivalent to the J2G3, is it (still) correct?
- EN 10250-2: regards steel forgings. Is it correct that S355J2G3 belongs to this Norm?

In the version of EN 10025 we have at work, S355J2G3 is included as a non-fine-grain having 27kJ resilience at -20°C, but a customer has objected about that and written a non-conformity ("Quality Plan contains non-pertaining material").

Many thanks in advance to anyone who can throw some light...

Regards

i think that this document from CORUS can give you some good advice on EN 10025

European structural steel standard EN 10025 : 2004
Explanation and comparison to previous standards

EN 10025 : 2004 is the new European standard for structural steel. This leaflet shows the new grades, properties and the nearest equivalent grades from former standards including EN 10025 : 1993. The grade designation system is also explained.

Hi,
thank you very much. In the meanwhile I also did a research with the help of our Quality Dept., and found out that very simply we were using the previous, out-of-date, version of the Norm... Very dangerous, indeed...
OK, problem solved!
