General Product Description
The high-strength structural steel at 700 MPa
Strenx® 700MC D/E is a hot-rolled structural steel made for cold forming, with a minimum yield strength of 700 MPa for stronger and lighter structures. Strenx® 700MC D/E meets or exceeds the requirements of S700MC in EN 10149-2.
Typical applications include a wide range of components and parts, such as demanding load-bearing structures. Strenx® 700MC D/E comes in coils, slit coils or cut-to-length sheets.

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.

Fabrication and Other Recommendations
Welding, bending and machining
Strenx® 700MC D/E has good welding, cold forming and cutting performance.
Strenx® 700MC D/E is a cold forming steel not suited for heat treatments at temperatures above 580°C since the material then may lose its guaranteed properties.
For information concerning fabrication, see SSAB´s brochures on www.ssab.com or consult Tech Support.
Appropriate health and safety precautions must be taken when bending, welding, cutting, grinding or otherwise working on the products.
