Microalloyed HD steels perform® and precidur®: thyssenkrupp Steel presents extensive hot strip and precision strip portfolio with excellent processing properties for automotive construction at EuroBLECH

• perform® HD – particularly good processing behavior for automotive construction
• precidur® HSM HD – maximum forming capacity for safety-relevant components
• Sample products from perform® and precidur® as well as other innovative steels will be presented by thyssenkrupp Steel from 25 to 28 October at the EuroBLECH trade show in Hannover, Hall 17, booth E33
• Presentation by thyssenkrupp Steel on "bluemint® Steel and the transformation of steel production at thyssenkrupp Steel Europe" on 27 October 2022 from 2:00 p.m. to 2:30 p.m. in the EuroBLECH Presentation Area, Hall 26, booth L60

Highly ductile microalloyed fine-grained steels are the first choice when significantly improved formability is required for complex component geometries in the axle or wheel suspension area. thyssenkrupp Steel has developed perform® HD as hot-rolled wide strip and the particularly close-tolerance precidur® HSM HD precision strip for this purpose. The special crystalline structure of the highly ductile microalloyed grades ensures stable mechanical properties. New in the range: microalloyed perform^® HD steels in the yield point range from 315 to 550 MPa (hot-rolled wide strip) and the two newly developed grades precidur^® HSM 380 HD and precidur^® HSM 420 HD (precision strip). Chassis steel CH-W^® 660Y760T is now also available hot-dip galvanized. The latter is the lightweight solution for single-skin control arms and comparable demanding components.

perform® HD steels for optimum component-related material selection

Due to their good processing behavior, hot-rolled microalloyed steels have proven their worth in automotive construction – especially in the areas of chassis and seats. The new high-ductility (HD) grades from thyssenkrupp Steel offer convincing features, with a uniform property profile tailored to the intended use at the same time as an increased forming potential. "The new micro-alloyed HD steels are characterized by a significantly narrower range of mechanical properties compared to the standard and have an increased elongation after fracture," says product manager Arne Schreiber. "With the higher-strength grades, the component weight can additionally be reduced. perform® HD steels are ideally suited for seat components such as cushion side members and seat rails or in the axle or wheel suspension area."

precidur^® – that little bit extra for complex components

precidur^® is used in almost all branches of industry. Particularly in the case of safety-relevant components, functional and design aspects are playing an increasing role alongside reliability – which demands the highest forming capacity of the basic material. Hot-rolled fine-grained steels such as precidur^® HSM 380 HD and precidur^® HSM 420 HD are particularly suitable for this purpose. They are characterized by symmetrical strip profiles and the rolled mill edge. Compared to proven microalloyed fine-grain structural steels, they make increased forming potential possible with the same strength.

The advantages of microalloyed perform® HD steels at a glance:

·         Improved cold formability for complex component geometries

·         Guaranteed narrower range of mechanical parameters compared to VDA 239-100 and DIN EN 10149-2 standards

·         Significantly increased elongation after fracture

·         Lightweight potential through sheet thickness reduction

·         Narrowest thickness tolerances for hot-rolled wide strip

·         Excellent surface quality

·         Reduction of production costs in the stamping shop thanks to application-specific property profile

thyssenkrupp is looking forward to face-to-face encounters and stimulating industry discussions at EuroBLECH 2022. Visit the booth from 25 to 28 October 2022 in Hall 17, booth E33.
