316l Lembaran Tahan Karat
316L stainless steel sheet ialah a rendah karbon, keluli tahan karat austenit dikenali untuk:
- Outstanding corrosion resistance, especially in chloride-rich or acidic environments
- Excellent weldability, suitable for complex fabrication
- Kekuatan mekanikal dan kemuluran yang baik
- Durability under harsh or industrial conditions
- Penerangan
316L stainless steel is a keluli tahan karat austenit karbon rendah, berasal daripada 316, with carbon content typically ≤ 0.03%. The low carbon content prevents sensitization during welding, making it ideal for applications requiring high corrosion resistance and durability.
316L is widely used in marin, kimia, farmaseutikal, and food processing industries due to its excellent corrosion resistance and stability.
Key Properties of 316L Stainless Steel Sheet
1. Exceptional Corrosion Resistance
- Highly resistant to chloride corrosion, air laut, and acidic environments
- Performs better than 304 dalam pitting and crevice corrosion
- Sesuai untuk coastal, kimia, and high-humidity environments
2. Kebolehkimpalan Cemerlang
- Low carbon content reduces risk of grain boundary carbide precipitation
- Allows welding without post-weld annealing
- Sesuai untuk complex fabrication and structural applications
3. Good Mechanical Strength
| Harta benda | Nilai Biasa |
|---|---|
| Kekuatan Hasil | ≥ 170 MPa |
| Kekuatan Tegangan | 485 – 620 MPa |
| Pemanjangan | ≥ 40% |
| Kekerasan | ≤ 95 HRB |
- Moderate strength with high ductility
- Can be cold worked to increase strength without significant loss of corrosion resistance
4. Rintangan Suhu Tinggi
- Mengekalkan good corrosion resistance at elevated temperatures
- Can operate continuously up to ~870°C in oxidizing conditions
5. Non-Magnetic Nature
- Austenitic structure ensures non-magnetic properties in annealed state
- Magnetic response may appear after severe cold working
Special Features of 316L Stainless Steel
