Stainless steel 316/316L
Material type: High Corrosion Resistance, Marine Grade, FDA-Compliant, Weldable, Low Carbon
Premium corrosion-resistant stainless steel grades (316/316L) for precision CNC machining, ideal for harsh environments, marine, chemical and medical applications where 304 falls short
Process compatibility
Material Color
Silver
Material advantages
- Superior corrosion resistance to 304, withstanding seawater, brine, concentrated chemicals and high-humidity environments (ideal for coastal EU/NA facilities).
- 316L (low carbon) eliminates carbide precipitation during welding, ensuring corrosion resistance in welded CNC components—critical for medical and food processing compliance.
- FDA-compliant for direct food/medical contact, meeting EU (CE) and North American (FDA) regulatory standards.
- Good high-temperature stability, suitable for industrial components exposed to sustained heat (up to 870°C short-term).
- Non-magnetic and ductile, compatible with precision CNC milling/turning and post-weld finishing.

Material shortcomings
- 20–30% more expensive than 304 (raw material + machining), due to molybdenum content (enhances corrosion resistance).
- Slightly lower machinability than 303; requires specialized cutting tools to avoid work hardening.
- Not cost-effective for general-purpose applications where 304 meets performance needs.
