Q: What is the material of DC06 coil?
A: DC06 coil is a cold-rolled low-carbon steel strip/coil for ultra-deep drawing under the European standard (DIN EN 10130) system. It belongs to interstitial (IF) steel, and its core characteristics are ultra-low carbon, high plasticity, and excellent deep-drawing formability.
Q: What do "DC" and "06" in DC06 represent respectively?
A: "DC" is an abbreviation for "Drawing Cold," meaning for cold stamping; "06" represents the stamping grade, with higher numbers indicating stronger stamping formability.
Q: What is the core difference between DC06 and DC01-DC05?
A: The main difference lies in its deep-drawing performance and mechanical properties. DC06 is an ultra-deep-drawing grade with lower yield strength (110-170MPa), higher elongation (37%-43%), an r-value (thickness anisotropy coefficient) ≥2.1, and an n-value (work hardening index) ≥0.22, making it suitable for more complex deep-drawing parts.
Q: What are the applicable standards for DC06 coils?
A: Commonly used standards include European DIN EN 10130, Chinese Q/BQB 408-2018, and Japanese JIS G 3141, etc. Different standards have slight differences in allowable deviations in composition and performance.
Q: What are the different types of DC06 coils based on their surface condition?
A: Common surface conditions include ordinary surface (O), pickled surface (P), passivated surface (C), and oiled surface, etc., which can be selected according to subsequent processing and rust prevention requirements.
