Q: What is the chemical composition range of DC01?
A: C≤0.12%, Mn≤0.60%, P≤0.045%, S≤0.045%, Al≥0.020%, with the remainder being Fe and trace impurities.
Q: What is the yield strength range of DC01?
A: 140–280 MPa (EN 10130).
Q: What are the tensile strength and elongation of DC01?
A: Tensile strength 270–410 MPa, elongation after fracture A80mm≥28%.
Q: What are the plastic strain ratio r90 and hardening index n90 of DC01?
A: There are no mandatory requirements for r90 and n90, making it suitable for simple molding.
Q: What are the effects of low C and low Mn on the properties of DC01?
A: It ensures high plasticity and cold formability, reduces work hardening, and facilitates bending, stamping, and welding.
