316l Stainless Sheet
316L stainless steel sheet is a low-carbon, austenitic stainless steel known for:
- Outstanding corrosion resistance, especially in chloride-rich or acidic environments
- Excellent weldability, suitable for complex fabrication
- Good mechanical strength and ductility
- Durability under harsh or industrial conditions
- Description
316L stainless steel is a low-carbon austenitic stainless steel, derived from 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 marine, chemical, pharmaceutical, 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, seawater, and acidic environments
- Performs better than 304 in pitting and crevice corrosion
- Ideal for coastal, chemical, and high-humidity environments
2. Excellent Weldability
- Low carbon content reduces risk of grain boundary carbide precipitation
- Allows welding without post-weld annealing
- Suitable for complex fabrication and structural applications
3. Good Mechanical Strength
| Property | Typical Value |
|---|---|
| Yield Strength | ≥ 170 MPa |
| Tensile Strength | 485 – 620 MPa |
| Elongation | ≥ 40% |
| Hardness | ≤ 95 HRB |
- Moderate strength with high ductility
- Can be cold worked to increase strength without significant loss of corrosion resistance
4. High Temperature Resistance
- Maintains 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
