Monel Hot Rolled Vs Cold Drawn Round Bar
Hot Rolled Monel Round Bar
- Wider size range & larger diameters available
- Good for structural and rough machining stock
- Lower cost, shorter lead time on ready sizes
- Black mill scale surface before finishing
Monel Cold Drawn Round Bar
- Tighter dimensional tolerance & smoother surface
- Better for precision shaft and fastener machining
- Improved mechanical strength after cold work
- Preferred for bright, polished finish stock
