Stainless steel strip is a cold-rolled, precision-engineered flat product characterized by high corrosion resistance, strength, and versatility. Typically thinner than sheets (thickness: 0.005–6.0 mm, width: 3–2,000 mm), it is supplied in coils or cut lengths for diverse industrial applications137. Its properties stem from chromium (≥10.5%) and alloying elements like nickel or molybdenum, which enable a self-healing oxide layer for rust prevention, alongside superior formability and temperature resilience (-196°C to 800°C)35.
Stainless steel strips are categorized by microstructure, each with distinct attributes:
Grade Type | Key Alloys | Properties | Typical Uses |
---|---|---|---|
Austenitic | 304 (06Cr19Ni10), 316L | 18% Cr, 8% Ni; non-magnetic, excellent corrosion resistance & formability | Food processing, medical devices, architecture34 |
Ferritic | 430, 436 | 12–17% Cr; magnetic, moderate corrosion resistance, cost-effective | Automotive exhausts, appliances16 |
Martensitic | 410, 1.4028Mo | 13–14% Cr, added Mo; heat-treatable, high hardness | Surgical tools, valve components, cutlery59 |
Duplex | 2205 | Mixed austenite-ferrite; high strength, chloride resistance | Chemical plants, offshore platforms2 |
Specialized grades:
Precision strips (e.g., SUS304-CSP) for electronics, thickness down to 0.005 mm7.
Automotive-specific alloys (e.g., 436L, 445) meeting stringent bendability and salt-spray resistance standards6.
Thickness: 0.05–5.0 mm (common range), with ultra-thin foils ≤0.1 mm for micro-components17. Tolerances as tight as ±0.01 mm for critical applications5.
Width: Slit to 3–1,500 mm, tolerances ±0.15 mm13.
Surface finishes:
2B: Matte, standard cold-rolled finish.
BA: Mirror-like, bright-annealed.
No.3/No.4: Directional satin polish for aesthetics34.
Cold Rolling: Enhances surface smoothness and dimensional accuracy via twenty-high mills69.
Heat Treatment:
Annealing: Restores ductility using gas-protected continuous furnaces.
Temper Rolling: Adjusts hardness (e.g., soft, 1/4 hard, full hard)39.
Surface Engineering: Brushing, embossing, or passivation (nitric/citric acid) to boost corrosion resistance35.
Slitting & Leveling: Precision width cutting (±0.1 mm) and flattening to eliminate coil curvature17.
Global Standards: ASTM A240 (US), JIS G4305 (Japan), GB/T 4237 (China), EN 10088 (EU)36.
Tolerance Norms: ISO 9444 (hot-rolled wide strip) and ISO 9446 (narrow strip) define dimensional deviations, though now superseded810.
Testing Protocols:
Mechanical: Tensile strength (>600 MPa), elongation (>4%)5.
Corrosion: Copper-accelerated acetic acid salt spray (CASS) ≥48 hours without rusting6.
Strips are coiled on wooden reels, wrapped in burlap or kraft paper, and secured with steel straps to prevent transit damage. Coil weights range from 500 kg to 5 tons, with moisture-proofing for marine shipments15. Export packaging adheres to seaworthy standards (e.g., wooden matting for containers)24.
Automotive: Exhaust systems (409/436), trim (445), springs (301 hard temper)16.
Medical: Scalpels (410), implantable device casings (316L), sterilization trays39.
Electronics: Battery contacts, EMI shields, connectors (precision SUS304 strips)7.
Construction: Roof flashing, decorative panels (BA or brushed finishes)34.
Packaging: High-tensile strapping (>600 MPa) for heavy equipment and marine cargo15.
