The hot-dip galvanized steel DX56D in accordance with EN 10346 is a highly developed material that has been specially developed for extremely demanding cold forming processes. With the material number 1.0963 (formerly 1.0322), it belongs to the group of mild steels and is classified as a special deep-drawing grade. This special design is ideal for highly complex forming processes that require maximum formability combined with outstanding surface quality. Thanks to the integrated hot-dip galvanizing process, the DX56D also offers reliable corrosion protection, making it resistant even in harsh environments. The wide range of available coatings – +Z, +ZF, +ZA, +ZM, +AZ and +AS – also enables targeted adaptation to individual requirements.

The DX56D is characterized by an extremely low yield strength and tensile strength, which gives it its exceptionally high formability. These mechanical properties make it particularly suitable for special deep-drawing processes where uniform material distribution and low springback are important. This means that even components with very complex geometries can be produced precisely without cracking or hardening. The combination with a hot-dip galvanized protective coating also offers excellent resistance to corrosion. Depending on the type of coating selected, additional requirements – such as increased heat protection (+AS), improved coefficient of friction or optimized weldability – can be met.

DX56D is typically used in the automotive industry, particularly in the production of body parts with high degrees of deformation, such as outer skin components, interior door panels or complex structural parts. This steel is also used in the production of household appliances, white goods and technical housings, where both filigree design and durability are required. DX56D is also used in electrical engineering and general mechanical engineering wherever the highest demands are placed on forming behavior, dimensional accuracy and corrosion resistance.

Compared to DX54D, which is also suitable for deep drawing, DX56D offers even greater formability. Both materials belong to the category of special deep-drawing grades, but while DX54D already stands for very good deep-drawing properties, DX56D is intended for applications with particularly high demands on material elongation and form complexity. This is achieved by the even lower yield strength and tensile strength of DX56D, which makes the material even easier and more uniform to form into complicated shapes. However, this outstanding formability also means that DX56D has a lower load-bearing capacity in comparison. It is therefore primarily the first choice where formability takes precedence over mechanical strength.

The hot-dip galvanized steel DX56D in accordance with standard EN 10346 is a high-quality solution for applications where maximum formability combined with excellent corrosion protection is required. As a special deep-drawing grade, this material is ideal for demanding forming processes with complex geometries. Thanks to the large number of available coatings, DX56D can be optimally adapted to specific requirements – whether in terms of thermal resistance, surface quality or further processing methods. Compared to DX54D, DX56D offers even greater freedom in shaping, which is why it is a preferred material for high-precision and high-quality components, particularly in the automotive industry and white goods production.
