Steel Billets 3SP

1. Product Overview
Steel Billets 3SP are semi-finished long steel products, precision-cast to a standard 130mm x 130mm square cross-section, primarily serving as the essential feedstock for rebar, wire rod, and light section rolling mills. Engineered for secondary refining and hot rolling, these billets deliver superior metallurgical homogeneity and surface consistency, directly reducing mill wear and energy consumption during processing. For global steel converters, the 3SP grade represents a strategic balance of cost efficiency and mechanical reliability, ensuring consistent output in high-volume construction and infrastructure supply chains.

2. Key Specifications & Technical Characteristics

• Chemical Composition (ladle analysis, max %): C: 0.18–0.22%, Mn: 0.60–0.80%, Si: 0.15–0.30%, P: ≤ 0.040%, S: ≤ 0.045%

• Grade Standard: 3SP (conforming to ASTM A36 / BS 4449 equivalent for downstream rolling)

• Physical Form: Square billets; corner radius: 10–15 mm

• Dimension: 130mm x 130mm (tolerance: ± 2 mm)

• Length: 6m, 9m, or 12m (± 50 mm); custom lengths available on contract

• Density: 7.85 g/cm³

• Surface Condition: Descaled; free of deep cracks, laps, or excessive pipe; visual inspection per ISO 3763

• Packaging Options: Naked in bundles (2 MT per bundle) + 4 steel straps; optionally edge-protected for sea freight

• Shelf Life: Indefinite under dry, covered storage (corrosion surface layer does not affect remelting/rolling performance)

3. Core Industrial Applications

• Primary Industries: Construction rebar mills, wire rod manufacturing, light structural sections, and foundry feed

• Specific Use Cases:

  • Rolling into TMT/rebars (Fe 415/500 grade) for high-rise and bridge construction

  • Drawing into low-carbon wire for fencing, mesh, and nails

  • Forging into small structural components (angles, channels, flats)

• Performance Advantage: The 3SP chemistry and consistent section geometry reduce rolling mill pass adjustments by 15% compared to generic billets; lower phosphorus/sulfur content minimizes hot shortness and cold cracking in final products.

• Cost Efficiency: Optimized for single-pass rolling at 950–1050°C, lowering energy consumption per ton by 8–10% versus higher-alloy billets for equivalent tensile applications.

4. Competitive Advantages

• Quality Consistency: Every cast tracked via heat number; third-party mill certificates (EN 10204 Type 3.1) available per shipment.

• Supply Reliability: Dedicated 200k MT/month production capacity from integrated DRI-EAF-LRF-CCM mills; shipping schedules guaranteed with delay penalties.

• Logistics Capability: Strategically located near deep-water ports (Rotterdam, Houston, Shanghai, Jebel Ali) with in-house stevedoring and flatbed transport.

• Price Competitiveness: Direct mill pricing with low working capital requirement – indexed to Platts/Mysteel with fixed premium for quality parameters.

• Sustainability: Produced using minimum 70% recycled scrap + electric arc furnace; Scope 2 emissions below 0.25 t CO₂/t billet; available with green steel certification.

• Technical Support: Free rolling simulation and ladle trim advisory; dedicated metallurgical engineer per key account.
