Structural steel material- S355 equivalent

Structural steel material- S355 equivalent

(OP)
Hi
This is PVK Raju and iam presently working in engineering industry and subcontract of navel and ship building. one of our customer requirement as per drawing raw material is S355 or equivalent material
How do find the S355 (structural steel-EN 10025)equivalent materials. Can anybody have in this please help me.

Thanks & regards,
P V K Raju

RE: Structural steel material- S355 equivalent

S355 or equivalent almast always means : use S355 - or better.
using "equivalent" USA steel grades (instead of EU steel according to the 10025) usually means a higher % C, which will make you fall into more difficult steel groups to qualify for (both WPS as weldor).

There are (3?) ISO/TR (technical rapport) which give similar classification, I'll check for their references this evening.

Hi
Thanks for your response
As you said S355 or equivalent means Use S355 or better

We are planing to use S355 equivalent material like 1) S355K2G3 2)S355J2+N
3) S355K2+N etc

The above grade materials are equivalent? Please give your comment

Thanks & Regards
PVK Raju

RE: Structural steel material- S355 equivalent

The grades you have suggested such as S355J2+N are S355 material already, so you are not substituting for another material?

the additional information is describing the rolling process and other properties. I would advise to check if the design requirements are more stringent than just '355 or equivalent', as it sometimes is.

hope that helps
regards
