The hot-dip galvanized steel DX57D in accordance with the EN 10346 standard is a top product among cold-formable steels. With the material number 1.0853, this material belongs to the group of mild steels and is classified as a super deep-drawing grade – the highest category in terms of formability. Thanks to its exceptionally low yield strength and outstanding plastic properties, DX57D is specially designed for the production of components with extreme shape requirements. The hot-dip galvanized surface – available in the coating types +Z, +ZF, +ZA, +ZM and +AS – also offers excellent corrosion protection and extends the range of applications for this material in many industrial sectors.

The DX57D impresses with its maximum formability and high surface quality. With its very low yield strength, correspondingly low tensile strength and above-average uniform elongation, even highly complex geometries can be realized without cracking, material embrittlement or springback. The very fine microstructure allows uniform forming even with a minimum bending radius.

The selection of different galvanizing types – from classic galvanized (+Z) to zinc-iron (+ZF), zinc-aluminium (+ZA), zinc-magnesium (+ZM) and aluminium-silicon (+AS) – offers application-specific benefits such as improved corrosion protection, better weldability and increased temperature resistance. This combination of excellent formability and versatile surface adaptability makes DX57D a premium material in the field of sheet metal processing.

The DX57D is used wherever the highest forming demands are placed. In the automotive industry, for example, it is used for outer skin components, complex body parts or deep-drawn structural components where a flawless surface and precise shaping are crucial. This material is also used in the manufacture of household appliances, medical devices, electrical housings or technical components, especially when standard deep-drawing grades reach their limits. Thanks to its high formability, DX57D can be used to produce particularly delicate, load-optimized or design-oriented components.

In direct comparison with the already highly formable DX56D, the DX57D offers even better properties in terms of deep-drawing capability. While DX56D as a special deep-drawing grade provides an excellent basis for complex forming processes, DX57D as a super deep-drawing grade goes one step further. Its even lower yield strength and higher uniform elongation make it possible to carry out even extremely demanding forming processes with maximum precision and minimal risk of material failure. However, the processing of DX57D requires particularly precise process control, as the high formability is accompanied by lower mechanical strength. In applications where resilience and stability after forming play a greater role, DX56D may therefore be the more suitable choice despite its lower formability.

The hot-dip galvanized steel DX57D is a material of the highest forming class that has been specially designed for technically and aesthetically demanding applications. As a super deep-drawing grade, DX57D meets even the highest requirements in terms of precision, surface quality and shape complexity. The available coating types also enable targeted adaptation to different environmental conditions and processing technologies. Compared to other deep-drawing grades such as DX56D, DX57D offers even better forming properties, making it a preferred material in the automotive, household appliance and electronics industries. If you are looking for maximum formability combined with reliable corrosion protection, DX57D is a high-performance and future-proof solution.
