Description
S1100 Plus steel is a hot-rolled structural steel with a minimum yield strength of 1100 MPa. The material feature excellent flatness and surface quality, providing an outstanding finish to the final products. Typical applications include a wide range of parts and components such as demanding load-bearing structures.
S1100 Plus steel benefits
- Exceptional weldability with matching strength, elongation and toughness across a weld
- Very good bendability and surface quality
- Superior consistency guaranteed by close tolerances
- High impact toughness which provides for good resistance to fractures
Dimension Range
S1100 Plus steel is available as cut to length sheets in thicknesses of 4.0 - 8.0 mm. S1100 Plus is available in widths up to 1600 mm and lengths up to 13 000 mm depending on thickness. Please contact your sales representative for more information regarding dimensions.
Mechanical Properties
| Thickness (mm) | Yield strength Rp0.2 (min MPa) | Tensile strength Rm (MPa) | Elongation A (min %) | Min. inner bending radius for a 90° bend |
| 4.0 - 6.0 | 1100 | 1130 - 1350 | 10 | 3.5 x 1 |
| 6.1 - 8.0 | 1100 | 1130 - 1350 | 10 | 4.0 x 1 |
The mechanical properties are tested and guaranteed in both longitudinal and transverse direction.
Impact Properties
| Test direction | Min. Impact energy for Charpy V 10x10 mm test specimens |
| Longitudinal | 27 J/ -40 °C |
| Transverse | 27 J/ -20 °C |
Impact testing according to EN ISO 148-1 is performed on thicknesses ≥ 6mm. For thicknesses between 6.0 - 8.0 mm, sub-size Charpy V-specimens are used. The specified min value is then proportional to the cross-sectional area of the specimen compared to a full-size specimen (10x10 mm).

Fabrication and Other Recommendations
Welding, bending and machining
S1100 Plus steel has extremely good weldability with the same minimum guarantees for strength, elongation and impact toughness across a weld as in the parent material, as long as our recommendations are followed.
S1100 Plus steel has good forming performance.
S1100 Plus steel has obtained its mechanical properties by quenching and subsequent tempering. The properties of the delivery condition cannot be retained after exposure to temperatures in excess of 400 °C.
Appropriate health and safety precautions must be taken when welding, cutting, grinding or otherwise working on this product. Grinding, especially of primer coated plates, may produce dust with a high particle concentration.
