Description
The high-strength structural steel at 600 MPa
S600MC steel is a hot-rolled structural steel made for cold forming, with a minimum yield strength of 600 MPa for stronger and lighter structures.
S600MC steel meets or exceeds the requirements of EN 10149-2.
Typical applications include a wide range of components and parts, such as demanding load-bearing structures. S600 MC comes in coils, slit coils or cut-to-length sheets.
Dimension Range
S600MC steel is available in thicknesses of 2.00-10.00 mm and widths up to 1600 mm as coils, slit coils or cut to length sheets in lengths up to 16 meters.
Mechanical Properties
Thickness (mm) | Yield strength ReH (1) (min MPa) | Tensile strength Rm (MPa) | Elongation A80 (2) (min %) | Elongation A5 (min %) | Min. inner bending radius for a 90° bend (4) |
| 2.00- 3.00 | 600 | 650- 820 | 13 | 16 (3) | 0.7 x t |
| 3.01- 6 | 600 | 650- 820 | 16 | 1.1 x t | |
| 6.01- 10 | 600 | 650- 820 | 16 | 1.4 x t |
The mechanical properties are tested in the longitudinal direction.
(1) If ReH is not applicable then Rp 0.2 is used.
(2) A80 value applies for thicknesses < 3.00 mm
(3) A5 value applies for sheet thickness t ≥ 3mm.
(4) For both longitudinal and transverse direction.
Impact Properties
| Grade | Min. impact energy for longitudinal testing, Charpy V 10x10 mm test specimens |
| S600MC D | 40 J/-20 °C |
| S600MC E | 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 (ladle analysis), %, max.
| C | Si | Mn | P | S | Al | Nb | V | Ti |
| 0.12 | 0.21 | 1.90 | 0.025 | 0.010 | 0.015 | 0.09 | 0.20 | 0.15 |
(1) If the material is to be hot-dip galvanized according to category A or category B in EN 10149-2 this must be specified at the time of order. Other galvanizing classes with higher Si-content are available after agreement.
(2) Sum of Nb, V and Ti = max 0.22%
The steel is grain refined.

Fabrication and Other Recommendations
Welding, bending and machining
S600MC steel has good welding, cold forming and cutting performance.
S600MC steel is a cold forming steel not suited for heat treatments at temperatures above 580°C since the material then may lose its guaranteed properties.
Appropriate health and safety precautions must be taken when bending, welding, cutting, grinding or otherwise working on the product.
