Skin Pass Mild Steel S 235 Jrg2 Hot Rolled Steel Coil

S235JR is the European standard non-alloy structural steel, equivalent to Q235B, that is, low carbon structural steel, mostly used for welding, bolt connection, riveting structure.

S235JRG2 steel may be a specific one and has no different classes. it had been regulated in EuroNorm EN 10025 superseded by EN 10025-2 (2006) and therefore the new designation is simply S235JR. Both editions affect "structural" steels.

The designation given is that the symbolic one, the numerical designation of fabric 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 optional , optional only)
G2- Rimming steel not allowed.

More characteristics of this plain 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%)
