Core Advantages and Typical Applications of DC05 COIL
Core Advantages and Typical Applications of DC05 COIL
Core Advantages
Excellent Formability
Elongation ≥38%, plastic strain ratio (r-value) ≥1.6, particularly suitable for complex forming processes such as deep drawing and stretching
Erichsen cupping value ≥9.0mm, strong resistance to thinning
Excellent surface quality
Cold-rolled and annealed, surface roughness Ra ≤0.8μm
Smooth or matte finish options, suitable for direct spraying or electroplating
Stable mechanical properties
Tensile strength 250-360MPa, yield strength 120-210MPa
Hardness 80-120HV, low work hardening rate
Excellent weldability
Low carbon content (C ≤ 0.06%) ensures excellent weldability
Suitable for processes such as resistance spot welding and laser welding
High cost-effectiveness
Lower cost compared to DC06
A more affordable option than stainless steel and aluminum alloys
Typical Applications
Automotive Manufacturing
Body panels: Door inner panels, hoods, trunk lids
Structural components: Seat frames, instrument panel brackets

Selection Recommendations
When balancing cost and formability, DC05 is the preferred choice. COIL
For ultra-deep drawing requirements (such as automotive fuel tanks), it is recommended to upgrade to DC06 COIL.
High-strength steel (such as HX340) is recommended for load-bearing components.
Quality Control Key Points
Incoming Material Inspection: Tensile Properties, Cupping Test, Surface Quality
Processing Control: Die Clearance, Blank Holder Force Setting
Storage Requirements: Moisture- and rust-resistant, recommended use within 6 months
