EN 10025-3 steel grade is for weldable fine grain structural normalized steel in S275N, S275NL, S355N, S355NL, S420N, S420NL, S460N and S460NL steel plate.
S355N steel is a structural steel grade. S means structural steel, 355 means min yield strength for thickness less 16mm expressed in Mpa, NL mean the delivery condition.
The Chemical is max composition of product analysis:
| Grade | C % | Si % | Mn % | P % | S % | V % | AL % | Cr % |
| S355NL | 0.180 | 0.500 | 0.9-1.65 | 0.025 | 0.020 | 0.120 | 0.020 | 0.300 |
| Cu % | Mo % | Nb % | Ni % | Ti % | N % | |||
| 0.550 | 0.100 | 0.050 | 0.300 | 0.050 | 0.015 |
Nominal thickness = 63(mm) CEV max = 0.43
Nominal thickness from 63 to 100 (mm) CEV max = 0.45
For long products the P and S content can be 0.005% higher
For railway application a maximum S content of 0.01% may be agreed at the time of enquiry and order
If sufficient other N-binding elements are present the minimum total Al content does not apply
Cu content above 0.4% may cause hot shortness during hot forming

| Grade | Thickness(mm) | Min Yield (Mpa) | Tensile(MPa) | Elongation(%) | Min Impact Energy | |
| S355NL | 8mm-100mm | 235Map-275Mpa | 470-630Mpa | 22% | -50 | 27J |
| 101mm-200mm | 285Mpa-315Mpa | 450-600Mpa | 21% | -50 | 27J | |
| 201mm-250mm | 275Mpa-285Mpa | 450-600Mpa | 21% | -50 | 27J | |
| The min impact energy is longitudinal energy | ||||||
