DC07 Cold-Rolled Steel for Asymmetric Deep-Drawn Housings
Published
DC07 is a cold-rolled grade for deep-drawing requirements. A housing with deep walls, local features or an asymmetric outline calls for coordinated material, blank and forming decisions. Defining corners, visible surfaces and trimming requirements helps turn trial results into a practical purchasing specification. Jiangsu Gaozhen handles enquiries by grade, dimensions and processing requirements.
Where DC07 fits in deep-drawing selection
DC07 is a cold-rolled grade for deep drawing and can be assessed for parts with demanding drawn shapes. Unlike a sheet bent along a single line, a drawn housing develops a base, walls and corners inside the tooling. These regions do not deform in the same way. Material selection should respond to that forming requirement rather than simply favouring a larger grade number.
At purchasing stage, identify deep walls, local features and areas that will later be pierced or flanged. This information is more useful than overall length and width alone and gives the material supplier and fabricator a clearer basis for trial material.

Planning trials for an asymmetric housing
Consider an asymmetric cover with a straight wall on one side, a curved transition on the other and a mounting feature in the base. Trials should show whether these regions can form together, not merely whether the target depth is reached. Surface waviness, unusual thinning near corners and the position of subsequent mounting holes all belong in the sample review.
Keep records through the actual sequence of blanking, drawing, trimming, piercing and flanging. Associate stage samples with the same drawing revision and record sheet orientation, lubrication and tooling settings. This makes it easier to locate the stage at which a problem appeared.
Information to include with a material enquiry
Provide both the finished-part drawing and the developed blank. The first defines the required shape; the second supports discussion of material flow and trimming allowance. For a design still under development, mark critical corners, fixed assembly surfaces and locations where changes are possible.
Specify thickness together with its tolerance and distinguish appearance criteria for visible and concealed surfaces. Coil enquiries also need feed direction, slit width and receiving-equipment requirements; sheets need cut length and flatness. Where painting follows, include the pre-paint surface in sample review. Retain the agreed samples, drawings and delivery condition together for repeat orders.
Will changing the grade alone solve drawing cracks?
Not necessarily. Start with the crack location in relation to the blank edge, corners and process stage, then review tooling, lubrication, orientation and incoming condition. Blank or process changes may be as relevant as a different grade. Link trial records to the material batch before deciding whether to revise the process or assess another material.
DC07 dimensions and supply enquiry
The Gaozhen DC07 product page lists these catalogue dimensions: Thickness range: 0.2-6.0 mm; Width range: 1000/1250/1500 mm. These values support specification discussions; confirm the required combination of gauge, width and condition for the material.
For this cold-rolled component, discuss cut-to-length sheets or slit coil against the developed blank. Include the final drawing and scope for cutting, CNC shearing or bending.
