What is DX56D Steel?
DX56D is a deep-drawing low-carbon steel for high-forming needs, with about 0.01-0.08% carbon and 0.2-0.5% manganese, ideal for cold forming. “DX” denotes flat steel, “56” its strength, and “D” its drawing grade. It meets EN 10346-2015 and GB/T 2518-2019 standards, and EU steel number is 1.0963. It is produced via hot-dip galvanizing, with finishes like Z, ZA, ZF, ZM, AZ, and AS for automotive, appliance, and construction uses, requiring deep drawing and shape complexity.
How Does DX56D Compare To Other Deep-Drawing Steels?
SteelPRO Group’s DX56D steel is produced using an advanced hot-dip galvanizing process. Due to its low carbon content and zinc coating, it offers superior formability and corrosion resistance compared to other deep drawing steels, making it particularly suitable for applications requiring complex forming.

Production Processes of DX56D Steel
At SteelPRO Group, we understand the demands of our customers for material processing accuracy and performance. Our DX56D galvanized steel uses advanced processing technology to ensure that each batch of products can meet industry standards and provide reliable support for your production:
- Raw material selection: We select low-carbon raw materials to ensure that the steel has excellent formability and ductility, ensuring excellent performance in subsequent processing.
- Hot rolling process: During the hot rolling process, we heat the raw materials to about 1200°C and then roll them to form them to ensure that the steel plate reaches the required thickness and uniformity, laying the foundation for the subsequent cold rolling and galvanizing processes.
- Cold rolling process: Through cold rolling, we further thin the steel plate, improve the surface quality and consistency, and make the finished steel have a smooth surface for subsequent processing and use.
- Annealing treatment: During the annealing process, we heat the steel to about 700-750°C to enhance its ductility and ensure the excellent performance of the steel in complex forming.
- Galvanizing process: We use advanced hot-dip galvanizing technology to coat the steel surface with a layer of zinc to provide excellent corrosion resistance and ensure that the product can be used for a long time in wet and harsh environments.
