Material Features
- Molybdenum alloying improves resistance to chloride corrosion, good for seawater, brine and chemical media; better corrosion resistance than 304
- Heat resistance: Long-term service temperature ≤800℃, excellent low-temperature toughness
- Good weldability. 316L low-carbon variant provides superior intergranular corrosion resistance after welding
- Noticeable work-hardening by cold rolling; suitable for springs under moderate fatigue requirements
Applications
Marine components, chemical equipment, seawater pipelines, pharmaceutical machinery, food processing equipment, environmental facilities, precision gaskets, corrosion-resistant shielding parts, sensor components, etc.
Material Comparison
| Grade | Key Characteristics |
|---|---|
| 316 | Molybdenum added, good chloride resistance, moderate elasticity |
| 316L | Low-carbon grade, preferred for welding, better resistance to intergranular corrosion |
| 304 | No molybdenum, poor chloride resistance, lower cost |
| 301 | High work-hardening property, mainly for spring contacts, inferior corrosion resistance |
