Strenx® 650MC D/E
General Product Description
The high-strength structural steel at 650 MPa
Strenx® 650MC D/E is a hot-rolled structural steel made for cold forming, with a minimum yield strength of 650 MPa for stronger and lighter structures. Strenx® 650MC D/E meets or exceeds the requirements of S650MC in EN 10149-2.
Typical applications include a wide range of components and parts, such as demanding load-bearing structures. Strenx® 650MC D/E comes in coils, slit coils or cut-to-length sheets.
Dimension Range
Strenx® 650MC D/E 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.

The mechanical properties are tested in the longitudinal direction.
1) If ReH is not applicable then Rp0.2 is used. On thicknesses >8 mm the minimum yield strength may be 20 MPa lower.
2) A80 value applies for thicknesses < 3.00 mm.
3) A5 value applies for thicknesses ≥ 3.00 mm.
4) For both longitudinal and transverse direction.

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.
