Key Properties:
1.Corrosion Resistance:
Excellent resistance to pitting and crevice corrosion in chloride environments.
- Suitable for maritime applications due to resilience against saltwater.
2. Mechanical Strength:
- High yield and tensile strength, typically around 70,000 psi.
- - Retains good ductility and toughness at both high and low temperatures.
- 3. Temperature Resistance:
- - Can withstand temperatures up to approximately 870°C (1600°F) in oxidizing environments and up to 925°C (1700°F) in continuous service.
- 4. Hygienic and Non-Magnetic:
- - The smooth surface makes it easy to clean, which is vital in food and pharmaceutical industries.
- - Non-magnetic nature reduces the risk of magnetic contamination.
- 5. Fabrication:
- - Easily welded and machined although care must be taken to minimize carbide precipitation in the heat-affected zone during welding.
