S355 JR Yield Strength
S355 is named based on it's minimum yield strength of 355 Mpa (N/mm2).
Here is the table showing reduction in yield strength based on thickness
Up to 16 mm - 355 Mpa
16 mm < t ≤ 40 mm - 345 Mpa
40 mm < t ≤ 63 mm - 335 Mpa
63 mm < t ≤ 80 mm - 325 Mpa
80 mm < t ≤ 100 mm - 315 Mpa
100 mm < t ≤ 150 mm - 295 Mpa
S355 ultimate tensile strength ranges also varies based on thickness.
Up to 3 mm - 510 Mpa to 680 Mpa
3 mm < t ≤ 100 mm - 470 Mpa to 630 Mpa
100 mm < t ≤ 150 mm - 450 Mpa to 600 Mpa
