Description
The high-strength structural steel at 1100 MPa
S1100MC steel is a hot-rolled structural steel made for cold forming, with a minimum yield strength of 1100 MPa for stronger and lighter structures.
These cut-to-length sheets feature excellent thickness accuracy and surface quality in relation to strength level, providing an outstanding finish to the final products.
Typical applications include a wide range of parts and components such as demanding load-bearing structures.
Dimension Range
S1100MC steel is available as cut to length sheets in thicknesses of 3.00 to 8.00 mm, widths up to 1700mm and lengths up to 16 meters.
Mechanical Properties
| Thickness (mm) | Yield strength ReH (1) (min MPa) | Tensile strength Rm (MPa) | Elongation A5 (min %) | Min. inner bending radius for a 90° bend (2) |
| 3 - 8 | 1100 | 1250- 1450 | 7 | 4.0 x t |
The mechanical properties are tested in the longitudinal direction.
(1) If ReH is not applicable then Rp 0,2 is used.
(2) For both longitudinal and transverse direction.
Impact Properties
| Test direction | Min impact energy for Charpy V 10x10 mm tests specimens |
| Longitudinal | 27 J/ - 40 °C |
Impact testing according to EN ISO 148-1 is performed on thicknesses ≥ 6mm.
The specified minimum value corresponds to a full-size specimen.
Chemical Composition, %
| C, max | Si, max | Mn, max | P, max | S, max | Al, min |
| 0.15 | 0.5 | 1.8 | 0.020 | 0.005 | 0.015 |
The steel is grain refined.
In addition Nb, V, Cr, Mo, B and Ti may be used.

Fabrication and Other Recommendations
S1100MC steel has good welding, cold forming and cutting performance.
S1100MC steel is not suited for applications requiring hot working or heat treatments at temperatures above 200°C since the material then may lose its guaranteed properties.
