SPFH590 Pickled Coil: Material Preparation for Progressive Stamped Structural Attachments
Published
For continuously fed stampings in SPFH590 pickled steel, consider both material requirements and coil-to-line compatibility. Slit width, camber, edges and coil-end handling are practical checks before structural-component production. Jiangsu Gaozhen handles enquiries by grade, dimensions and processing requirements.
SPFH590: material and applications
SPFH590 is a high-strength hot-rolled forming grade for automotive applications, listed by Gaozhen as pickled sheet and coil. It can be assessed for continuously fed structural stampings against part strength requirements and the stamping route. Pickling removes scale, but suitability for a production line also depends on shape, edges and feeding conditions.
Reinforcements, connecting brackets and mounting seats have different shapes and die-station arrangements. Relate the grade and developed width to the forming operations, then observe feeding and forming with a trial coil to connect the stock specification to the actual production process.

Parts and Material in Progressive Stamping
Structural attachments produced by progressive stamping include reinforcement plates, connecting brackets, and mounting bases. They are typically made from slit coil fed into a progressive die that performs blanking, forming, trimming, and cut-off in sequence. Coil width, slit camber, and the condition of coil ends directly affect feeding stability. Thickness and flatness may vary at coil ends and joints, so these should be inspected and either cut off or accommodated before the die entry. Station positioning depends on feed pitch and guiding; width tolerance and edge quality must match the feeding mechanism. A single sample forming well does not mean continuous production conditions are identical; a trial run should be arranged before production, recording feeding, positioning, and forming performance.
Purchasing Specifications and Batch Planning
When purchasing SPFH590 pickled coil, specifications should state nominal width, thickness, inner diameter, coil weight range, and slitting requirements. Stating only nominal slit width is insufficient; width tolerance, edge condition, and feeding direction should also be specified, as edge quality and camber affect continuous feeding. Coil end and joint limits should be clarified in the order, such as permitted joint count or length. For batch production, arrange a trial run and record incoming width, camber, and feeding performance as a reference for subsequent lots. Delivery lots should be coordinated with the production schedule to avoid prolonged storage or frequent coil changes that affect feeding stability.
Is Nominal Slit Width Sufficient?
No. Slit width should be specified together with width tolerance, edge condition, and feeding direction. In progressive feeding, width tolerance affects guiding clearance, while edge burrs or camber can disturb feed pitch and station positioning. Purchasers should state these parameters in the order and verify them during incoming inspection.
SPFH590 dimensions and supply enquiry
The Gaozhen SPFH590 product page lists these catalogue dimensions: Thickness range: 0.8-20 mm; Width range: 1000/1250/1500 mm. These values support specification discussions; confirm the required combination of gauge, width and condition for the material.
Discuss pickled stock alongside cut-to-length, slitting and drawing-based cutting. Include the later manufacturing route for parts requiring bending or joining.
