Pickled and Annealed Sheets

Description

1. Product Overview
   Pickled and Annealed Sheets are high-quality cold-rolled steel products that have undergone a controlled pickling and annealing process to remove surface oxides and improve mechanical properties. They are widely used in automotive, construction, appliances, and heavy engineering industries where surface quality and formability are critical. The key value proposition lies in their superior surface cleanliness, enhanced ductility, and excellent processing performance in downstream manufacturing. Strategically, they serve as a foundational input material in high-value industrial supply chains requiring precision, consistency, and reliability.
2. Key Specifications & Technical Characteristics

• Material: Low-carbon steel / carbon steel base (industrial grade variants such as SPHC, SAE 1006–1018 equivalent)
• Processing: Acid pickled (oxide scale removal) and annealed (heat-treated for softness and formability)
• Surface Condition: Clean, smooth, oxide-free surface
• Thickness Range: Typically 0.3 mm – 6.0 mm (customizable upon request)
• Width Range: 600 mm – 1500 mm (or slit-to-width specification)
• Hardness: Low hardness, optimized for deep drawing and stamping
• Coil/Sheet Form: Available in coils or cut-to-length sheets
• Packaging: Standard export seaworthy packaging (steel strapping + anti-rust paper + protective film)
• Shelf Life: Up to 12 months under dry, controlled storage conditions

3. Core Industrial Applications
   Pickled and Annealed Sheets are extensively used in automotive body panels, structural components, and precision stamping parts due to their excellent formability and surface quality. In the construction sector, they are applied in structural framing, roofing systems, and fabricated metal components. They are also critical in appliance manufacturing, including refrigerators, washing machines, and HVAC systems, where smooth finishing and consistent mechanical performance are required. Compared to untreated hot-rolled steel, these sheets offer significantly improved dimensional accuracy, reduced processing defects, and lower tooling wear, resulting in higher manufacturing efficiency and reduced operational costs.
