As a leading exporter and manufacturer of high-quality structural steel plates, Gangsteel specializes in producing S420N grade steel per EN 10025-3.
S420N grade steelmeans a high-strength normalized fine-grain structural steel with 420 MPa minimum yield strength and 40 J impact toughness at -20°C.
The designation S420N is broken down as follows:
|
Symbol |
Meaning |
|---|---|
|
S |
Structuralsteel |
|
420 |
Minimum yield strength = 420 MPa(for thickness ≤ 16 mm) |
|
N |
Normalizeddelivery condition |
|
(No L) |
Impact tested at -20°C (40 J longitudinal) |
S420NL= same grade, but L for -50°C impact (27 J).

S420N grade steelmeans:
It is a high-strength fine-grain steel for welded structures in moderate cold.
N= Normalized delivery — ensures fine-grain structure and consistent toughness.
Only impact test:
Same strength and chemistry.
420 MPa minimum yield strengthfor thickness ≤ 16 mm.
Yes— CEV ≤ 0.48, no preheat needed up to 50 mm.
Heavy welded structureslike bridges, cranes, offshore in moderate cold climates.
