S235JRG2,S235JRG2 steel plate,EN S235JRG2 steel, EN 10025 S235JRG2.

S235JRG2 steel 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 It was regulated in EuroNorm EN 10025 superseded by EN 10025-2 (2006) and the new designation is just S235JR.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 S235JRG2 steel 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.)
