General Product Description

Strenx® Section 650MC is a cold-formed steel section made of hot-rolled, high-strength steel with a minimum yield strength of 650 MPa.

Its high-strength combined with naturally stiff form enables construction of stronger and lighter structures. Typical applications include demanding load-bearing structures in the lifting, handling and transportation segments.

Strenx® Section 650MC is available as U-section. Other shapes and variations are available upon request. The maximum length of the sections is 826.770", cut-to-length sections are available upon request.

The mechanical properties are tested in the longitudinal direction.

1) If ReH is not applicable then Rp0.2 is used. On thicknesses >0.315" the minimum yield strength may be 2.9 ksi lower.

Tolerances

Tolerances according to EN 10162 when applicable. For Strenx® Sections with material thickness over 0.314" SSAB guarantees same tolerances as given in EN 10162 for thickness range 0.236"-0.314". Narrower tolerances are available upon request.

Delivery Conditions

The sections are roll formed from thermomechanically rolled steel.

Fabrication and Other Recommendations

Welding, bending and machining

Strenx® Section has good weldabilility, including corner region, and it is suitable for thermal cutting. All the common welding methods are suitable with matching or undermatching consumables.

Sections can also be sawed and machined with regular tools. Bending of the sections is also possible, please contact Tech Support for further instructions. 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 product.
