📄 Product Description: DD15 Sheet Steel — Low-Carbon Steel for Extra Deep Drawing
🧾 General Technical Characteristics
DD15 (1.0349 according to EN 10111) is a high-quality low-carbon hot-rolled steel specially developed for extra deep drawing and complex forming operations. Compared to DD13, DD15 offers even higher ductility and superior formability without risk of cracks.
Thanks to its excellent workability, DD15 is widely used in the production of components requiring complex shapes while maintaining material integrity.
⚙️ Applications
- Automotive industry (e.g., stamping of complex body parts)
- Manufacturing of tanks, reservoirs, and containers
- Household appliance production
- Forming parts with high degrees of drawing
- Agricultural machinery and mechanical engineering
- Any products requiring maximum ductility for stamping
📈 Key Advantages
- ✅ Extra deep drawing without cracking
- ✅ High ductility and stable material structure
- ✅ Excellent weldability with all common methods
- ✅ Smooth and clean surface for coating or painting
- ✅ Fully compliant with EN 10111 standard
