They are different. DC01 is an ordinary cold plate and DC03 is a cold plate for stamping. The chemical composition and mechanical properties of the two are different.DC01 – This grade can be used for simple forming work, for example Bending, embossing, beading and pulling are used. DC03 – This grade is suitable for forming requirements such as Deep drawing and difficult profiles suitable.
DC01 and DC03 are both cold-rolled low-carbon steels (EN 10130) used for cold forming, with the primary difference being that DC03 offers superior deep-drawing and ductility properties compared to the standard forming capability of DC01. DC03 has lower yield strength and higher elongation, making it suitable for more complex, deeper shapes, while DC01 is best for simple bending and general fabrication.
What is DC01 steel?
DC01 (1.0330) is a European standard cold-rolled, low-carbon, non-alloy quality steel designed for general cold forming, bending, and welding, with excellent surface quality. Formerly known as St12 or FeP01, this ductile, low-strength metal is ideal for automotive panels, home appliances, and intricate metal components.
What is DC03 steel?
DC03 steel is a cold-rolled, low-carbon deep-drawing quality steel defined by European standard DIN EN 10130. Known for excellent formability, high surface finish, and good weldability, it is tailored for complex shaping, pressing, and bending applications. It is commonly used in automotive, appliance, and general engineering sectors.
The DC in DC01 represents DIN1623-1 (German cold-rolled sheet standard) flat steel products, low-carbon steel cold-rolled strips and sheets. DC is the abbreviation of DC in DIN1623-1 Flatproductsofsteel products. Alloy steel cold rolled strip and sheet.
The deep drawing performance levels represented by 01, 02, 03, and 04 are different. The larger the number, the better the tensile properties.
Therefore, DC01, DC02, DC03, DC04 represent different grades of cold-rolled steel, and their deep drawing properties are also different.
01 Ordinary material, 020304 deep drawing material, the better the deep drawing performance
DCO1 is usually not used for stretching, only for simple bending
DC02 can be used for shallow stretching, but is usually only used for bending.
DC03 can be said to be a stretched board
DC04 finally has the best tensile properties and can be deep drawn to a standard relationship.
