Plasticity and deformability: these are the strengths of our steels for bolts and screws
Wire rods with high plasticity and deformability
Suitable for cold or hot forging, thanks to the particular characteristics of the surface quality, ductility and micro purity.
Applications:
- Fasteners for automotive industry
- Fasteners for mechanical industry
- Bolts for structural uses
- Rivets
- Extruded or cold-formed parts, including downstream mechanical parts
- Other uses.
