Q: What is DC04 material?
A: DC04 is a cold-rolled low-carbon aluminum-killed steel for deep drawing, as defined in European standard EN 10130, commonly used in complex stamping parts.
Q: Which core standards does DC04 comply with?
A: It mainly complies with GB/T 5213-2019 and EN 10130, covering chemical composition, mechanical properties, surface quality, and dimensional tolerances.
Q: What are the old Chinese designations and ISC numbers for DC04?
A: The old designation is SC1, and the Chinese ISC number is U40078.
Q: What are the key differences between DC04 and DC01/DC03/DC05?
A: In ascending order of deep drawing grade, DC04 has better formability than DC01/DC03, but slightly lower than DC05; it has lower yield strength and higher elongation, making it suitable for more complex deep drawing.
Q: What are the typical heat treatment conditions for DC04? A: Mostly annealing + leveling (S state) is used to ensure excellent deep drawing performance and stable surface quality.
