S700MC Pickled Steel for High-strength Thin-walled Components
Published
S700MC is a high-strength thermomechanically rolled cold-forming structural steel, and pickled coil is often used for thin-wall parts with defined thickness and section requirements. For purchasing, clarifying the processing validation from coil to part is more practical than comparing grades alone. Jiangsu Gaozhen handles enquiries by grade, dimensions and processing requirements.
S700MC: material and applications
S700MC is a high-strength thermomechanically rolled cold-forming structural steel. The pickled coil surface helps with subsequent painting or inspection before forming. The direct reason to select it is usually a design requirement for yield strength and weight reduction while the part remains primarily cold-formed. For thin-wall parts, higher material strength does not remove the need to check stiffness, connections and stability when setting thickness and section. Purchasing should provide the complete drawing, design thickness, forming sequence and joining method at the inquiry stage so the supplier can judge whether pickled coil is a suitable supply form. If the part involves bending, flanging or welding, edge cracking, bending direction, springback and heat-affected zones should be put on the process evaluation list before the order, not discovered during volume stamping.

Typical Parts and Processing Route
Pickled coil is commonly used for thin-wall structural parts such as brackets, reinforcements and connecting plates formed to drawing. The actual material demand depends on thickness, blank size and forming method shown on the drawing. The route usually starts with decoiling and blanking or laser cutting, then bending, stamping or roll forming, possibly followed by welding and surface treatment. Edge-crack tendency relates to shear or laser cut quality, material direction and bend radius, and should be confirmed by trial parts. Springback affects angles and assembly gaps and should be measured at tryout or first-off. Welding heat-affected zones influence high-strength steel properties, so welding parameters and inspection requirements should be set by process evaluation rather than fixed values in the purchase order.
Purchasing Confirmation and Trial Arrangement
For S700MC pickled coil, confirm the complete drawing and manufacturing route before arranging trial parts. The drawing should include thickness, critical sections, bend locations, hole positions and joining method. The manufacturing route should state the cutting method, forming sequence, welding arrangement and surface treatment requirements. The supplier can then judge whether coil width, surface condition and slitting method are suitable. At the trial stage, run a small batch through the actual cutting and forming steps, recording edge condition, bend-angle springback and dimensional or appearance changes in heat-affected zones. The purchase order can specify incoming surface condition, packaging and identification, plus trial quantity and acceptance method, but should not fix a universal bend radius or welding parameters; those come from process evaluation. If design considers thinning with high-strength material, purchasing should submit stiffness, fastener specification and stability check results together, rather than substituting thickness on strength alone.
Does Higher Strength Mean Direct Thinning?
No. Higher strength in S700MC can support weight-reduction design, but whether a thin-wall part can be thinned is also governed by stiffness, connection strength and stability. Purchasing should ask design to provide checks for the target thickness and arrange trial parts to validate forming and joining; thickness should not be substituted based on grade strength alone.
S700MC dimensions and supply enquiry
The Gaozhen S700MC 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.
