HR700LAS made by voestalpine impressively exceeds standard specifications.
HR700LAS is a hot-rolled, micro-alloyed steel that not only meets the requirements of VDA 239-100, but is also highly suitable for challenging component geometries such as narrow edge radii, particularly in combination with punched edges and the flanging of punched holes. Material standards define the minimum requirements and are an important reference for steelmakers and users. The material data sheet VDA 239-100 specifies hot-rolled and cold-rolled flat steel products for automotive applications. The HR700LAS steel grade made by voestalpine Stahl GmbH exceeds the requirements of forming and resistance to cracking and impressively outperforms conventional hot-rolled, micro-alloyed steels and reinforces the hot-rolled drive product group of ultralights steels.
The future calls for even more. Light-weight automotive design calls for sophisticated structural solutions. It is often not enough for materials to simply meet the standard specifications in order to reliably produce high-quality components. Technical feasibility requires above-average processing properties, most importantly excellent forming properties and a high degree of resistance to cracking.
More freedom of design. HR700LAS is a hot-rolled, micro-alloyed steel that not only meets the requirements of VDA 239-100, but is also highly suitable for challenging component geometries: narrow edge radii, particularly in combination with punched edges and the flanging of punched holes.
The HR700LAS steel grade permits crack-free component production and thus offers a high degree of design freedom for applications with thickness beginning at 2 mm, e.g. for chassis and seat components.
More than just intensively tested. Comprehensive pilot series show that the forming of punched edges with HR700LAS is still possible where other conventional micro-alloyed steels fail as a result of substantial cracking (see images).
