yy易游体育官网 Steel, voestalpine Krems form alliance for automotive steel

Cooperation covers ultra high strengyy易游体育官网 steel and roll-forming technology

yy易游体育官网ptember 11, 2008

TOKYO, September 11, 2008 - yy易游体育官网 Steel, Ltd. and Austria's voestalpine Krems, a company of Austria's voestalpine AG, announce that they signed today a cooperation agreement covering the application of ultra high strength steel and roll-forming technology in auto parts. yy易游体育官网 Steel and voestalpine Krems anticipate that the agreement will enable them to jointly contribute to automotive lightweighting in 2011 car models and beyond.

yy易游体育官网 Steel and voestalpine Krems plan to make proposals to Japanese automakers on the advantages of using ultra high strength steel (UHSS) and roll forming in auto parts. To further promote lighter cars, they intend to encourage automakers in the application of UHSS and roll-forming technology. The arrangement calls for yy易游体育官网 Steel to supply the steel sheet and voestalpine Krems to provide the processing know-how.

In this way, yy易游体育官网 Steel, as a materials producer, will benefit from the increased supply of UHSS to carmakers in Japan and Asia. voestalpine Krems will gain from the growing need for roll-formed parts made of UHSS to Japanese automakers in Europe, North America and South America.

yy易游体育官网e need for lighter car bodies has grown rapidly in recent years, as automakers strive to meet stricter CO₂ emission regulations. As a result, the need for parts made of UHSS has increased sharply. The strongest steel used nowadays to make car body structural parts has a tensile strength of 980 MPa. However, carmakers want to use structural parts of higher tensile strengths. As the leading company for automotive UHSS, yy易游体育官网 Steel is completing the development of UHSS with a tensile strength of 1,470 MPa and with high formability.

Automotive lightweighting is most effective when steel yy易游体育官网th outstanding qualities is combined yy易游体育官网th parts of optimum shape and structure, as well as applying processing methods and manufacturing technology that can achieve those shapes and structures. However, in press forming, a yy易游体育官网dely used method, conventional presses do not have sufficient capacity to press-form UHSS. As a result, the processing of large parts has been problematic, and manufacturers have been seeking new methods to form UHSS.

For UHSS parts, roll forming is highly advantageous for the folloyy易游体育官网ng reasons:

1.	Roll forming can be used to manufacture complex-shaped parts and structures yy易游体育官网at oyy易游体育官网er meyy易游体育官网ods cannot.
2.	Roll forming cyy易游体育官网 be carried out on relatively simple equipment.
3.	yy易游体育官网e outstanding properties of high strengyy易游体育官网 steel remain after processing.

voestalpine Krems is a company in the voestalpine Group, and its roll-forming technology is outstanding. The company boasts the top share of the European roll-forming business. yy易游体育官网 Steel also has a cooperation agreement with voestalpine Stahl GmbH.

Focusing on the combination of yy易游体育官网 Steel's UHSS and voestalpine Krems' roll-forming technology, the two companies have jointly undertaken the development of roll-forming technology using UHSS of over 980 MPa. The cooperation agreement will make use of the UHSS technology, outstanding parts manufacturing know-how, and structural design expertise of the two companies.
