Hot-rolled
Steel for ship plate
This hot-rolled structural steel offers excellent weldability for ease of processing.
We exercise stringent control over the chemical composition and mechanical properties of our ship plate – ensuring products of consistent and reliable quality for demanding marine applications.
This is proven by an approval of manufacturer from DNV-GL and Lloyds EMEA.

Properties
Mechanical Properties
Ship plate has the following mechanical properties, measured transverse to the rolling direction:
| Lloyds EMEA | Grade A | |
|---|---|---|
| Min. yield strength ReH 1 | N/mm² | 235 |
| Tensile strength Rm | N/mm² | 400 - 520 |
| Min. elongation after fracture A | % | 22 |
| Impact test 2 | Temp. °C | - |
| Min. energy J | - |
1. Upper yield strength or 0.2% proof stress applies.
Elongation after fracture A uses test piece length L0 = 5.65√S0.
2. Impact strengths apply to thicknesses > 6 mm and are for standard test pieces only. Please contact us for details.
