Hot-rolled steel coil SAE 1006

Description

1. Product Overview

SPCC-grade cold-rolled steel sheet is a low-carbon, commercial-quality flat-rolled product refined through sequential cold reduction and annealing. It is primarily used in automotive components, home appliance panels, and general metal stamping where surface finish and thickness precision are critical. The key value proposition is its consistent mechanical properties and excellent paintability without additional surface treatment. Strategically, SPCC serves as the backbone of mid-tier precision manufacturing, bridging the cost-performance gap between hot-rolled and high-strength steels.

2. Key Specifications & Technical Characteristics

• Chemical composition (max %): C ≤0.12, Mn ≤0.50, P ≤0.040, S ≤0.045

• Grade / standard: SPCC (JIS G 3141), commercial quality (CQ)

• Physical characteristics: Flat sheet, matte finish (surface roughness Ra 0.4–1.5 μm), typical density 7.85 g/cm³, thickness range 0.3–3.2 mm, width up to 1,520 mm

• Packaging options: Anti-rust oiled paper interleaving, seaworthy wooden pallets or steel-framed bundles, shrink-wrapped with edge protectors

• Shelf life: 6 months under dry, covered storage (unexposed to condensation); oxidation-resistant oil coating extends to 12 months

3. Core Industrial Applications

• Automotive: Interior structural brackets, wheel covers, oil pan shields – SPCC’s uniform elongation enables complex stamping without edge cracking.

• Home appliances: Refrigerator liners, washing machine shells, microwave cavities – superior flatness reduces secondary grinding and painting defects by 30% versus HR steel.

• Lighting & furniture: Electrical enclosures, desk drawer slides – cost-efficient alternative to electrogalvanized steel where corrosion exposure is low but surface appearance matters.

• General manufacturing: Lock parts, tool cabinets, support channels – predictable spring-back behavior reduces die rework in progressive stamping lines.

4. Competitive Advantages

• Quality consistency: Full hard temper range (1/8H to full hard) with thickness tolerance ±0.03 mm across coil ends – validated by inline ISO 9001:2025-certified gauge control.

• Supply reliability: Three source mills with overlapping capacity, buffer stock held in Rotterdam, Houston, and Shanghai – 98.7% on-time dispatch record.

• Logistics capability: Split-container and LCL consolidation available for mixed gauge orders; 48-hour dispatch ex-warehouse for common sizes.

• Cost competitiveness: Direct annual mill contracts remove 2–3 distribution layers – priced at LME steel + flat conversion fee with no grade premium.

• Environmental benefit: 40% recycled content, EPD available, compliant with EU CBAM reporting requirements.

• Technical support: Full mill test certificates (MTC), SGS pre-shipment inspection option, and forming simulation data (no extra charge).

5. Commercial & Supply Information

• Minimum order quantity (MOQ): 20 MT (mixed gauges permitted within same width)

• Loading capacity: 22–25 MT per 20-foot container (depending on coil OD and pallet configuration)
