EN10111 DD11 steel plate surface quality

The surface quality of EN10111 DD11 steel plate usually has the following detailed requirements:

1. Smoothness: The surface of EN10111 DD11 steel plate should be smooth without obvious unevenness or wavy deformation to ensure stability during processing and use.

2. No cracks: There must be no cracks on the surface, especially after cold working, to ensure the strength and appearance integrity of the product.

3. No scratches: The surface is required to have no deep or obvious scratches to avoid affecting the coating, processing or the appearance and performance of the final product.

4. Oil film: An appropriate amount of anti-rust oil or other surface treatment may be required to protect the surface of EN10111 DD11 steel plate from oxidation and corrosion and ensure quality during storage and transportation.

5. Cleanliness: The surface should be kept clean without obvious stains, impurities or foreign matter to ensure the quality of subsequent coating, bonding or processing.

6. Coating suitability: If subsequent coating or surface treatment is required, the surface quality should meet coating adhesion and uniformity requirements.

7. Dimensional accuracy: May include dimensional accuracy requirements such as flatness, thickness tolerance, etc. to comply with design specifications and meet manufacturing standards.

8. Surface roughness: There may be specific surface roughness requirements to suit different processing or application needs.

These surface quality requirements are designed to ensure that EN10111 DD11 steel plates meet specific standards in all aspects to meet customer needs and adapt to different application fields.
