QStE700TM Pickled Steel for Cut, Bent and Joined Reinforcements
Published
QStE700TM is a grade in the high-strength hot-rolled steel series for automotive structures, listed as pickled coil in the Gaozhen product catalog. For reinforcement parts in heavily loaded equipment drawings, purchasers should confirm incoming condition and inspection items together with cut edges, bend corners, weld zones, and machining allowance. Jiangsu Gaozhen handles enquiries by grade, dimensions and processing requirements.
QSTE700TM: material and applications
QStE700TM belongs to the high-strength hot-rolled automotive structural steel family and is listed by Gaozhen as pickled sheet and coil. For reinforcements on heavy-duty equipment drawings, begin with the part’s function: connection, support or local reinforcement, followed primarily by bending or by cutting and welding.
Coordinate pickled surface condition, dimensions and delivery form with that route. Incoming hardness is one piece of material information rather than a replacement for the applicable standard and drawing. Include the full grade, standard, material-document requirements and inspection items in the same stock list.

Reinforcement Material and Processing Concerns
Reinforcement parts in heavily loaded equipment drawings are commonly bent plates, connection plates, or local stiffener plates. Processing usually starts with uncoiling, leveling, and cutting, followed by bending, welding, and machining. When specifying requirements based on the actual part, purchasers should confirm cut edges, bend corners, weld zones, and machining allowance item by item. For cut edges, state whether laser, plasma, or shearing is used, because heat effects and burr conditions differ and affect subsequent dressing allowance. For bend corners, evaluate against the drawing bend radius rather than judging formability from incoming hardness alone. For weld zones, confirm whether groove preparation, cleaning, and welding sequence are supported by process documents. For machining allowance, leave room for edge trimming, leveling, and post-weld machining.
Procurement Documents and Acceptance Terms
When purchasing QStE700TM pickled coil, the procurement documents should specify the governing standard, grade, delivery condition, dimensions, and drawing version, and clearly list inspection items including surface quality, dimensional tolerance, and material documentation. This is because cut edges, bend corners, and weld zones of reinforcements are sensitive to incoming consistency, and receiving based on hardness alone does not cover forming and welding preparation. Incoming hardness can be recorded at receipt but cannot replace complete material documentation. Purchasers should also confirm with the supplier the acceptance limits for the pickled surface, coil weight and leveling method, and whether drawing versions stay synchronized across partial deliveries. If downstream bending or welding is involved, list process items to be evaluated in the procurement documents for the processor to confirm with their equipment and tooling conditions, rather than presupposing conclusions at the purchasing stage.
Can QStE700TM and S700MC Be Mixed Directly?
A grade comparison table is not an authorization for interchangeability. Whether the two can be mixed should be confirmed item by item against the approved standard's technical requirements, including governing standard, chemical composition, mechanical properties, dimensions and surface condition, and the drawing's specific requirements for the reinforcement. Purchasers should require material documentation for the corresponding batch and complete an internal technical review before any change; without confirmation, do not directly substitute or mix.
QSTE700TM dimensions and supply enquiry
The Gaozhen QSTE700TM 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.
