📄 Product Description: DD14 Sheet Steel — Low-Carbon Steel for Deep and Extra Deep Drawing
🧾 General Technical Characteristics
DD14 (1.0389 according to EN 10111) is a low-carbon hot-rolled steel with enhanced properties for deep and extra deep drawing operations. DD14 offers excellent ductility, a uniform structure, and minimal risk of cracking, even during complex forming processes.
This material is positioned between DD13 and DD15 in terms of ductility and is intended for applications requiring greater drawing depth than DD13 but less than DD15.
⚙️ Applications
- Automotive industry (stamping of complex body parts)
- Manufacturing of tanks and reservoirs
- Production of household appliance components
- Mechanical engineering and agricultural machinery
- Hydraulic and pneumatic cylinders
- Products requiring high formability
