HPL +N Duro LCF

With HPL +N DURO LCF, Mannesmann is setting new standards for high-pressure precision steel tubes. Our material concept combines high fatigue strength with excellent process and operational reliability. This enables significantly thinner-walled tube designs โ€“ without compromising safety or service life. Developed for demanding hydraulic applications, HPL +N DURO LCF helps designers reduce weight, increase performance, and makes efficient use of installation space.

Next-generation materials for the powertrain

Our innovative materials combine maximum performance with significant weight reduction โ€“ for both conventional powertrains and electric vehicles. Mannesmannโ€™s KSG1000 high-performance steel offers approximately 20% higher strength with about 20% less weight, enabling more efficient drivetrain designs. Materials such as 23MnCrMo5 for intermediate shafts or 45MnB5 for side shafts deliver high torque almost instantly, thereby allowing for more compact, lighter transmissions.
