EN 1.0025-S235JRG2 Material and Different Classes

01/15/2008 7:02 AM

Can any body explain me EN 1.0025-S235JRG2 and its classes like ASTM A105. If you can give a link that is fine.

Hi,

Steel S235JRG2 is a specific one and has no different classes. It was regulated in EuroNorm EN 10025 superseded by EN 10025-2 (2006) and the new designation is just S235JR. Both editions deal with "structural" steels.

The designation given is the symbolic one, the numerical designation of material is 1.0038.

The symbolic designation means:

S- "Structural Grade"

235- minimum value of yield strength in MPa ( roughly 35 ksi) for thicknesses ut to 16 mm.

JR- Base steel (Charpy impact test not obligatory, optional only)

G2- Rimming steel not allowed.

More characteristics of this plain carbon steel available in long (Profiles, beams..) and flat products (sheet and plates) are:

Impact value (if specifically required)- 27 J at 20ºC

Carbon content:0.17% max. (0.20% for thicknesses over 40 mm)

Mn content: 1.40% max

P and S content: 0.045% max.

N content: 0.009% max (Not applicable if Al minimun is 0.020%)

ASTM steel A105 has different uses (can be applied to pressure service for example) even if it's a carbon steel too. The different grades refer to different strength grades.

If you want to use EN steels according to EN 10025, there are some other designations for different strength grades (for example S275 or S355 which have a higher yield strength.)

If you need carbon steel designations according to EN for pressure service you must consult the EN 10028 Part 2 standard.

Kwetz, I've rated this a good answer.

If they had a great answer button, I've have given you that.

Hi, my name is William, then I can substitute it for the ASTM-A36?

Hi William.

From a chemical composition point of view, the chemistry is a subset of A36, with the possible exception of the phos going out of spec at 0.045; the A36 limit for phos is 0.040.

the mechanical property requirement for a 36 is surprise surprise, minimum 36ksi Yield strength; as Kwetz has pointed out, themin for this spec is about 35 Ksi.

If the phos was under 0.040 and the yield strength was over 36ksi, I would approve a deviation.

But the authority to substitute or deviate lies with the customer, per the the order documents.

They should have no difficulty giving you such approval.

However, going the other way from A36 to this grade is more difficult, as A36 allows higher Carbon from 0.25 up to 0.29 depending on product and section.
