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.

Ready to upgrade?

You can improve the performance and reduce the weight of your equipment by upgrading from Strenx® 650MC to Strenx® 700MC. Using a steel with 8% higher yield strength means you can increase the equipment’s load-bearing capacity. Get in touch with our steel specialists at SSAB Tech Support or SSAB Knowledge Service Center for an update on upgrading.
