EN10111 DD11 cold rolled steel material properties

The material properties of EN10111 DD11 cold rolled steel are detailed as follows:

1. Chemical composition: Typical composition includes:
- Carbon content (C): usually below 0.12%.
- Manganese content (Mn): generally between 0.6% and 1.5%, which helps improve strength and hardness.
- Sulfur content (S) and phosphorus content (P): lower requirements to ensure welding performance and surface quality.

2. Mechanical properties of EN10111 DD11 cold rolled steel:
- Yield Strength: approximately between 170 and 360 MPa, depending on the specific production process and specifications.
- Tensile Strength: Generally in the range of 270 to 410 MPa.
- Elongation: Usually required to be above 25%, showing good ductility and suitable for general cold working operations.

3. Heat treatment characteristics: EN10111 DD11 cold-rolled steel usually does not require heat treatment, but its mechanical properties and microstructure can be improved by hot rolling or cold rolling.

4. Surface quality: A smooth, crack-free, and uniform surface is required to ensure that specific coating or subsequent processing requirements are met. Possible surface quality indicators include roughness, oil film requirements, etc.

5. Other characteristics: Depending on the specific application field and customer needs, the cold deformation behavior, plastic deformation window and other requirements of EN10111 DD11 cold rolled steel may also be considered to ensure that the expected processing performance and final product quality are met.
