Daimler, like many other leading car manufacturers, has developed its own steel standards to meet the high demands of modern vehicle construction. These specific OEM steel standards are designed to meet the individual needs of automotive production and guarantee maximum quality and reliability.

At the heart of the Daimler standards is the MBN series, which covers a wide range of steels – from soft, cold-rolled and hot-rolled steels to high-strength micro-alloys and multiphase steels. In addition to the MBN standard, the BQF (source approval) is crucial for series deliveries, as it ensures that only certain steelworks and production lines are approved.

We are happy to provide you with all the steel grades listed below for your projects – individually tailored to your requirements.

The MBN 11250 standard defines a wide range of steel grades that have been specially developed for the requirements of cold forming. From mild steel and low/micro-alloyed variants to innovative bake-hardening and IF steels through to dual-phase, TRIP and complex-phase steels, this standard covers all modern steel processing requirements.

Your benefits:
The versatile properties of the listed steel grades, such as high formability, excellent strength and optimized material properties, make them ideal for use in demanding applications. All materials are available in various designs and grades for your specific projects.

If you have any questions about the steel grades listed or require further information about our products, please do not hesitate to contact us!

The MBN 51251 (formerly MBN 11251) standard describes a diverse selection of high-quality steels that have been specially developed to meet the requirements of modern manufacturing processes. It covers a wide range of materials, including mild steels, low-alloyed and micro-alloyed variants as well as high-strength special steels such as dual-phase, TRIP and complex-phase steels.

Whether for applications that require maximum formability or for projects that rely on extreme strength and lightness – with the MBN 51251 standard you will find the right solution for every challenge.

All the steels listed are available in various configurations, including cold-rolled and hot-rolled variants that offer exceptional material properties thanks to modern processing methods.

Our company provides you with these steel grades precisely tailored to your individual requirements. We guarantee not only the highest material quality, but also comprehensive advice and reliable delivery.

The MBN 11257 standard defines a range of high-quality steel grades that have been specially designed for demanding applications in automotive, mechanical engineering and industrial production. This portfolio includes the following grades

These steel grades are characterized by their carefully balanced alloy composition and optimized microstructure, which ensure an excellent balance between strength, toughness and formability. Thanks to these properties, they can be used reliably in complex manufacturing processes without compromising on performance.

The steels defined in MBN 11257 offer ideal conditions, particularly in applications where precise component manufacture and high mechanical strength are required. Their technical performance supports both innovative lightweight solutions and robust, durable designs.

The portfolio includes different grades that are tailored to specific application requirements. Whether it is the moderately alloyed CR6Mn3 and CR6Mn6 variants or the particularly high-strength solutions such as CR22MnB5 and CR22MnB5-CS – each steel grade meets precisely defined parameters that help to optimize production processes.

Our company provides these steel grades for individual projects in accordance with the MBN 11257 standard. If you have any questions or require further information, please do not hesitate to contact us.
