Products Description
1. Base Material (Core Advantages of 316L)
- Standard Grade: AISI 316L / GB 022Cr17Ni12Mo2
- Key Composition:
- C ≤ 0.03% (ultra-low carbon, prevents intergranular corrosion after welding)
- Cr 16.0–18.0% (basic rust resistance)
- Ni 10.0–14.0% (stabilizes austenite structure and improves toughness)
- Mo 2.0–3.0% (resists chloride ion corrosion, pitting corrosion and seawater corrosion, far better than 304)
- Core Properties:
- Excellent corrosion resistance: resistant to seawater, salt spray, acid, alkali and chemical media, suitable for coastal, high-humidity and polluted environments
- Good weldability: low-carbon design, no rust or intergranular corrosion after welding
- Stable mechanical properties: tensile strength ≥ 485MPa, elongation ≥ 40%, maintains toughness from -196℃ to 600℃
- Hygienic & non-toxic: meets food and medical grade standards, easy to clean, no harmful substances
2. Coloring Process (PVD Vacuum Ion Plating)
- Adopts advanced PVD Physical Vapor Deposition process
- Forms a dense nano-scale metal film under high vacuum, with strong adhesion, wear resistance and fade resistance
- Eco-friendly, no VOC emissions, high temperature resistance (200–300℃)
- Retains full corrosion resistance of 316L with bright metallic luster

7. Comparison: 316L vs 304 Color Coated Stainless Steel
| Item | Color Coated 316L Stainless Steel | Color Coated 304 Stainless Steel |
|---|
| Corrosion Resistance | Excellent (with molybdenum), seawater & chloride resistant | Good for indoor & dry environments |
| Application Environment | Coastal, chemical, outdoor, high-humidity | Indoor, general commercial, dry areas |
| Weldability | No corrosion after welding | Risk of rust at welding joints |
| Service Life | 15–30+ years | 10–20 years |
| Price | Higher (for high-end projects) | Moderate (general decoration) |
8. Notes for Use
- For coastal/outdoor/humid environments, 316L is highly recommended
- Outdoor use: brushed/sandblasted + anti-fingerprint finish suggested
- Protect coating during installation; clean and maintain welded areas properly
