DC05EK Enamelable Steel According to DIN EN 10209: A Material with Special Properties

DC05EK enamelable steel according to DIN EN 10209 is a cold-rolled steel specifically developed for enameling. It is characterized by a range of properties that make it ideal for this application, particularly its smooth surface, good formability, enameling suitability, and tensile strength.

Properties

Higher Tensile Strength: Compared to DC04EK steel, DC05EK has a higher tensile strength of up to 500 MPa. This makes it a more robust and durable material that can withstand high mechanical loads.
Improved Workability: DC05EK steel is easier to bend and shape than DC04EK steel. This allows for the production of enamelled components with even more complex geometries and more intricate designs.
Reduced tendency for fish scaling: DC05EK steel, compared to DC04EK steel, is less prone to the formation of fish scales, a typical defect in enamelling. This leads to a more uniform and visually appealing enamelling result.
Good weldability: DC05EK steel has good weldability, which enables the production of enameled components from multiple individual parts.

Applications
DC05EK Enameling Steel is used in areas where, in addition to enamelability, high mechanical strength is required. These include:

Household appliances: Enamelled dishwashers, washing machines, refrigerators, and stoves with increased demands on robustness.

Sanitary ware: Bathtubs, sinks, and shower trays used in high-traffic areas.

Industrial plants: Enamelled containers, pipes, and equipment parts that are exposed to high temperatures and aggressive media.

Agricultural machinery: Enamelled bodies and attachments of agricultural machinery that must withstand extreme weather conditions.

Commercial vehicles: Enamelled driver’s cabs and bodies of commercial vehicles that are exposed to high mechanical stress and corrosion.

Processing
The processing of DC05EK Enameling Steel follows the general guidelines for processing cold-rolled steel. Before enamelling, the surface of the steel must be thoroughly cleaned and freed from impurities. The enamel is then applied to the steel and fired at high temperatures.

Conclusion
DC05EK Enameling Steel is a versatile and high-performance material that is ideal for enamelling when, in addition to enamelability, high mechanical strength and robustness are required. Its smooth surface, good formability, enamelability, tensile strength, and weldability make it a popular choice for a variety of applications.

Additional notes
In addition to DC05EK Enameling Steel, there are other enamelable steels on the market. The selection of the appropriate steel grade depends on the specific requirements of the application. It is important to observe the processing guidelines of the respective steel manufacturer to achieve optimal results in enamelling. Professional expertise is required for processing enamelable steels.
