What type of steel is DC01 plate?
A: DC01 is a cold-rolled low-carbon steel plate under the European standard system. It is clearly defined in the Chinese national standard GB/T 5213-2008 "Cold-rolled Low-carbon Steel Plate and Strip," and is mainly used in cold forming processes.
What are the core chemical components of DC01 plate?
A: The mass fraction percentages are: Carbon (C) ≤ 0.10%, Manganese (Mn) ≤ 0.50%, Sulfur (S) ≤ 0.025%, Phosphorus (P) ≤ 0.035%, and the residual aluminum content (Alta) ≥ 0.020%.
What is the tensile strength range of DC01 plate?
A: The tensile strength σb is 270-410 MPa. This strength range allows it to balance toughness and basic load-bearing capacity, making it suitable for conventional structural components.
What is the yield strength standard for DC01 plate?
A: Yield strength σs is 130-260 MPa, with some standards specifying a maximum yield strength not exceeding 280 MPa. A low yield-to-tensile strength ratio is beneficial for cold forming.
What is the elongation after fracture requirement for DC01 sheet?
A: Elongation after fracture δ5 ≥ 28%. Good elongation ensures it is less prone to cracking during bending and stamping.
