Cold-Rolled Steels offer various strengths and thicknesses.

Press Release Summary:



Measuring 0.28-1.0 mm thick, Docol Hard 450Y-750Y offers yield strength of 450-700 N/mm² and is suitable for light fittings, white goods, and furniture. Next level, ranging from 1.5-4.0 mm thick with yield strengths from 850-1,000 N/mm², is suited for lightweight containers as well as load-bearing beams, tubes, and profiles for building. With tensile strengths from 1,500-1,700 N/mm², highest strength steel ranges from 0.42-1.92 mm thick and is suited for heavy wear applications.

Thinner, Stronger and Thicker - SSAB is Launching New Steels with Many Attributes



SSAB Tunnplat is now launching Docol Hard - a range of advanced high strength, cold-rolled steels with various combinations of properties. The steels broaden the range of cold-rolled steels and give wide opportunities for developing new, more efficient products.

The new steels are included in the SSAB Swedish Steel range of advanced high strength, cold-rolled steels. Docol Hard combines strength and thickness in a way that gives the designer totally new scope for product development. The key to the properties of the new steels is the additional hardening achieved by a special rolling process.

"Docol Hard expands our range of advanced high strength steels and broadens the field of application for cold-rolled steels," says Karl-Inge Nilsson, Product Manager for Docol in the Sheet Steel Division of SSAB Swedish Steel. "Furniture, containers and safety parts are some of the areas in which the steels have already contributed to better and more effective products."

Docol Hard is produced in three product groups, with different combinations of strength and thickness.

Docol Hard 450Y-750Y has a minimum yield strength range of 450-700 N/mm2 and is characterized by being very thin at 0.28-1.0 millimetres. This group of Docol Hard supersedes conventional steels of the same or lower strength and offers new opportunities for forming high strength products with thin, sleek lines. Weight reductions of up to 50 percent and cost savings of up to 25 percent are attainable. Typical applications include light fittings, white goods and furniture such as shelving.

The next group of Docol Hard has higher yield strengths in the range of 850-1000 N/mm2 and thicknesses between 1.5 and 4.0 millimetres. Lightweight containers, load-bearing beams, tubes and profiles for the building industry, and various types of mechanisms such as seatbelt holders are examples of applications for which these steels are well suited. Mechanisms generally require the close tolerances on thickness that Docol Hard offers.

Finally, Docol Hard is also produced in the very highest strengths available, with tensile strengths between 1500 and 1700 N/mm2. These steels are among the strongest and hardest in the world, and are produced in thicknesses of 0.42 to 1.92 millimetres. These steels are suitable for applications in which the products are exposed to heavy wear or blows and shocks, and offer scope for developing products such as special low-weight containers.

Facts about SSAB Swedish Steel:
SSAB Swedish Steel is Scandinavia's largest steelmaker and one of the world's leading manufacturers of high-tensile steel. Through the acquisition in July 2007 of the North American steelmaker IPSCO we have taken an important step in our strategy to become the global leader in value added steel.

The product range in the steel sector covers now sheet, heavy plate and pipes. In Sweden, steel sheet is produced by SSAB Tunnplat and heavy-plate by SSAB Oxelosund. 2006, the number of employees was 8700 and the total crude steel production 4 million tonnes. The sales were about SEK 31 billion.

IPSCO is a leader in the development of high strength steel and pipe and the largest producer of plate in North America. 2006 the number of employees was 4300, the production capacity 3.9 million tonnes and sales 3.7 billion dollars.
