DC04

DC04
DC04 is a cold-rolled steel sheet grade specified in the German DIN standard (now the European EN standard). It is a cold-rolled low-carbon steel sheet for stamping. Its main features and information are as follows:
Performance: This deep-drawing grade cold-rolled steel offers excellent ductility and stamping properties, making it suitable for stamping applications requiring complex deformation. Its formability surpasses that of the general-purpose DC01 and the standard DC03, meeting medium-depth stamping requirements.
Chemical Composition (Typical Range): Carbon (C) content is typically ≤0.08%, manganese (Mn) ≤0.45%, phosphorus (P) ≤0.025%, sulfur (S) ≤0.025%, and aluminum (Al) ≥0.015% (acid-soluble aluminum). The composition is designed to ensure excellent ductility and weldability. Mechanical Properties: Yield strength is generally between 120-200 MPa, tensile strength is 270-350 MPa, and elongation after fracture (A80mm) is ≥38%. Its low yield strength and high elongation facilitate plastic deformation during stamping.
Applications: Commonly used in the manufacture of relatively complex stamped parts, such as body panels and interior trims in the automotive industry, components for refrigerators and washing machines in the home appliance industry, and other metal products requiring high forming precision.
Correspondence: It roughly corresponds to similar steel grades in other standards, such as SPCE (close to the Japanese JIS standard) and 08Al (deep drawing grade) in the Chinese GB standard. However, specific performance parameters may vary slightly depending on production processes and other factors.
