Using a specially developed manufacturing process, we manufacture high-strength hot-formed components for self-elevating installations.<\/p>\n

Offshore platforms stand on adjustable supports. During transportation, the supports retract and protrude upwards. On an offshore platform, they support the platform and anchor it to the seabed. Chords manufactured by voestalpine Grobblech strengthen the toothed rails of these supports and thus ensure safe operation in adverse conditions.<\/p>\n

Complicated manufacturing process<\/strong><\/p>\n

We have developed our technology for producing chords as hot-formed components in our own press shop. The starting material is a heavy sheet of high-strength fine-grained structural steel manufactured in our own rolling shop. Strips are cut from this slab and formed using a special tool on a hydraulic press with a maximum pressing force of up to 3,500 tons. The function of the tool is based on finite element calculations and guarantees a high level of shape accuracy. After hot forming, the chords are hardened with water and straightened. The edging, cut with a torch or milled on the long and short sides, is the final stage of the production process.<\/p>\n

Plates of high strength<\/span><\/span><\/h2>[vc_column_text animation_delay=”200″ css_animation=”bottom-to-top”]\n

High-strength heavy plates boast significant weight savings and optimal weldability.<\/p>\n<\/div>\n<\/div>\n

\n
\n

High stress<\/strong><\/p>\n

Cars and buildings keep getting bigger. When the size of a component is doubled in length, width, and height, the weight increases by a factor of 8, while the load-bearing cross-sectional surface area only increases by a factor of 4. This increases the stress, or weight in relation to the cross-sectional surface area, by a factor of two. High-strength steels can absorb these high loads, even if the weight of the component is reduced.<\/p>\n

Specific benefits<\/strong><\/p>\n

The lower weight of high-strength and ultra-high-strength heavy sheets saves money: the amount of input material, transportation costs, installation and foundation costs are significantly reduced. Costs are also saved during post-processing. Thanks to good weldability, work can be done faster and more efficiently. Significantly less welding consumables are required and weld inspection is made easier.<\/p>\n

Our program<\/strong><\/p>\n

High-strength heavy plates are available as fine-grained steel with a minimum yield strength of 620 and 700 MPa. Extra high strength heavy plates are available as special Voestalpine grades at 900, 960 and 1100 MPa.<\/p>\n
