MONEL 405 is the free-machining version of MONEL 400. It retains excellent corrosion resistance while adding sulfur to improve machinability. The alloy is primarily used for automatic screw machine products where efficient machining and corrosion resistance are required.
Chemical Composition (wt.%):
| Element | Content |
| Ni | Balance, ≥63 |
| Cu | 28-34 |
| Fe | ≤2.5 |
| Mn | ≤2.0 |
| S | 0.025-0.060 |
Mechanical Properties:
| Property | Typical Value |
| Tensile Strength | ≥480 MPa |
| Yield Strength | ≥170 MPa |
| Elongation | ≥35% |
Applications:
- Machined components
- Fasteners
- Valve parts
- Shafts and fittings
