Material advantages
- Excellent corrosion resistance to atmosphere, fresh water and mild chemicals, preventing rust in common environments.
- Good CNC machinability, achieving tight tolerances (±0.005mm) and smooth finishes (Ra ≤ 0.8μm) efficiently.
- FDA-compliant food-grade and non-toxic, suitable for food processing and indirect-contact medical components.
- Non-magnetic, ductile, and easy to weld, polish and post-process for diverse design needs.
- Cost-effective vs. high-grade stainless steels (e.g., 316L), balancing performance and production budget.

Material shortcomings
- Limited resistance to strong corrosive media (e.g., seawater, concentrated acids/alkalis), inferior to stainless steel 316L in harsh chemical environments.
- Lower high-temperature resistance; long-term use above 800°C may affect its mechanical properties and corrosion resistance.
- Prone to work hardening during CNC machining; requires proper cutting parameters to avoid tool wear and surface defects.
