Applications
- Mass Production of Nuts and Bolts.
- Used for high production by machining parts or mechanical components.
- Bushings, wedges.
- Valve parts.
- Rivets.
- Assemblies and shafts.
Characteristics:
- Within the entire 300 series, this stainless steel is the best in machinability.
- It is especially used when it is required to manufacture parts in series.
- It has excellent corrosion resistance in slightly corrosive conditions.
- Lower thermal conductivity than carbon steels, low-alloy steels, or tool-grade steels.
- It has good resistance to corrosion and oxidation.
