DC05 is a cold-rolled low-carbon steel sheet specified in the European standard (EN 10130), primarily used for stamping and forming applications (e.g., automotive and appliance components). Its chemical composition is primarily iron (Fe), with small amounts of other elements to ensure good plasticity and formability. The following is a typical chemical composition and function of stainless steel:
1. Main Chemical Composition (Mass Percentage)
Element Content Range (%) Function
C (Carbon) ≤ 0.02 - 0.06 Low carbon improves ductility and prevents stamping cracking
Mn (Manganese) ≤ 0.25 - 0.40 Strengthens ferrite and improves workability
P (Phosphorus) ≤ 0.025 - 0.035 Excessive amounts reduce toughness
S (Sulfur) ≤ 0.025 - 0.035 Excessive amounts form sulfides, affecting formability
Al (Aluminum) ≥ 0.015 - 0.060 Deoxidizer, refines grain size
Si (Silicon) ≤ 0.03 - 0.05 Residual element; excessive amounts reduce plasticity
Note: Specific content may vary slightly depending on production standards (e.g., EN 10130, DIN 1623).
2. Material Properties
Low strength, high plasticity: Suitable for complex forming processes such as deep drawing and bending.
High surface quality: Cold-rolled and annealed for a smooth surface (e.g., DC04, DC05, and DC06 have increasing ductility).
3. Common Applications
Automotive panels (doors, fuel tanks)
Appliance housings (washing machines, refrigerator panels)
General stamping parts (containers, brackets)
4. Comparison of Similar Grades
Grade (EN) C (%) Upper Limit Tensile Strength (MPa) Elongation (%)
DC01 0.10 270 - 410 ≥ 28
DC04 0.08 260 - 380 ≥ 34
DC05 0.06 250 - 360 ≥ 38
DC06 0.02 240 - 350 ≥ 42
Summary
DC05 is not a chemical element, but rather a low-carbon, cold-rolled steel sheet. Its core element is Fe, and its formability is optimized by strictly controlling the C and Mn contents. For precise composition information, it is recommended to consult the specific material standard or supplier's test report.
