3. Product Features

① Superior Corrosion Resistance

  • 304 grade resists rust in daily environments (e.g., moisture, weak acids); 316L adds molybdenum to withstand seawater, chemicals, and harsh industrial conditions.

  • No oxidation or discoloration even after long-term use, reducing maintenance costs for end-users.

② Food-Grade & Sanitary

  • Complies with FDA standards (for 304/316L grades), non-toxic and odorless.

  • Smooth 2B/BA surface prevents dirt accumulation, easy to clean—ideal for kitchenware, food containers, and beverage processing equipment.

③ High Temperature & Pressure Resistance

  • 321/310S grades maintain stability at temperatures up to 800°C (1472°F), suitable for boiler parts, furnace linings, and high-temperature pipelines.

  • Excellent tensile strength (≥515MPa for 304) ensures durability under mechanical stress.

④ Precision & Customization

  • Advanced rolling technology ensures uniform thickness (tolerance ±0.02mm) and flat surface—no warping or uneven edges.

  • Support customizations: width, length, surface finish, and hardness (soft/half-hard/full-hard) to match your specific production needs.

4. Application Scenarios

Kitchen & Food Industry

  • 304 Stainless Steel Coil: Used for making stainless steel pots, pans, cutlery, and food storage containers (safe for direct food contact).

  • 316L Stainless Steel Coil: Ideal for food processing machines (e.g., mixer blades, conveyor belts) and marine catering equipment (resists saltwater corrosion).

Medical & Sanitary Field

  • 316L grade (high purity, low carbon): Manufactures medical instruments (scalpels, forceps), hospital bed frames, and sterile room wall panels (anti-bacterial, easy to disinfect).

Automotive & Industrial

  • 430 Stainless Steel Coil: Used for auto exhaust systems, door handles, and decorative trims (cost-effective, good formability).

  • 321 Stainless Steel Coil: Applied in chemical pipelines, oil refinery equipment, and heat exchangers (resists acid/alkali corrosion).

Construction & Decoration

  • 8K Mirror Polished/Color-Coated 304 Coil: Used for building facades, interior wall panels, elevator doors, and furniture (elegant appearance, weather-resistant).

5. Quality Control

We strictly follow a 5-step quality inspection process to ensure zero defects:

  1. Raw Material Check: Test chemical composition of stainless steel ingots via 光谱分析 (Spectroscopy) to confirm grade compliance.

  2. Rolling Process Monitoring: Real-time monitoring of thickness, temperature, and speed via automated sensors.

  3. Surface Inspection: 100% visual check for scratches, pits, or discoloration; use ultrasonic testing for internal defects.

  4. Mechanical Testing: Conduct tensile, hardness, and corrosion resistance tests (salt spray test: 500 hours for 316L, no rust).

  5. Final Packaging Check: Verify coil weight, label accuracy (grade, 规格，batch number), and packaging integrity (waterproof film + wooden pallets).

6. Packaging & Shipping

Packaging Details

  • Inner layer: Moisture-proof PE film (prevents rust during storage).

  • Outer layer: Hard cardboard + steel strips (fix coils to avoid rolling).

  • Pallet: Fumigated wooden pallets (compliant with ISPM 15, suitable for international shipping).

  • Custom packaging available (e.g., seaworthy containers for long-distance transport).

Shipping Options

  • Port of Loading: Shanghai/Ningbo/Shenzhen (China); can arrange loading at your designated port.

  • Shipping Methods: Sea Freight (cost-effective for bulk orders, 15-30 days to major ports), Air Freight (fast, 3-7 days for small batches).
