SSAB Zero™

SSAB Zero™ steel is made using recycled steel and fossil-free energy.

The SSAB Zero™ EPDs and Certificate of Carbon Emissions is available on ssab.com. The availability of SSAB Zero™ products is subject to limitations and conditions of delivery have to be agreed upon separately.

General Product Description

Metal coated High Strength steels are designed for demanding structural applications that require galvanic corrosion protection and good formability in addition to high strength. Metal coated High Strength steels are designated according to their minimum guaranteed yield strength from 220 to 500 MPa. These steel grades comply with VDA 239-100 standard.

Dimension Range

SSAB CR300LA Zero is available in thicknesses of 1.00-2.00 mm and widths up to 1520 mm as coils.

Slit strip and cut to length sheets are available upon request.

Grade and coating specific restrictions on available dimensions may occur.

Tolerances

Hot-dip galvanized (GI, GA): Tolerances in accordance to EN 10143.

Customized dimensional and shape tolerances are available upon request.

Coatings

The metal coating options for SSAB ZeroTM products include:

Hot-dip zinc coating (GI) consists almost entirely of zinc (>99%). It is lead free, resulting in a small zinc spangle size. The coating provides good corrosion protection.

Galvannealed coating (GA) is a zinc-iron alloy coating having an iron content of approximately 10%. Galvannealed is produced by post-heat treatment in continuous hot-dip coating process. Galvannealed provides excellent resistance weldability and corrosion protection of painted products.

Grade specific availability of metal coatings for SSAB ZeroTM products is given in the Mechanical properties table (Coating).

SSAB ZeroTM metal coated products are available with surface quality for unexposed applications.

In addition to these coating masses, OEM specific coatings are available upon request.

Surface Treatments

Hot-dip galvanized (GI, GA): available as oiled and/or chemically passivated.

All surface treatments are in accordance with RoHS directive (2011/65/EU) and do not contain Chromium VI (Cr6+). Surface treatments provide only temporary surface protection during transportation and storage. In order to avoid corrosion damages, care must be taken to keep the products dry during transportation and storage. If they become wet, they must be separated and situated so that they are dried quickly.

Fabrication and Other Recommendations

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.
