Unibar 200

The softest grade in the Unibar portfolio, Unibar 200 is a primarily ferritic iron that offers remarkable machinability and excellent surface quality but limited strength and wear resistance. This grade has excellent noise, vibration damping, and thermal conductivity.

Unibar 250

Unibar 250 is a pearlitic-ferritic iron that, while still having exceptional machinability and a superb surface quality, provides a strong mix of strength and wear resistance over Unibar 200. Unibar 250 has outstanding noise and vibration dampening, heat conductivity, and vibration damping because of its graphite structure.

Unibar 300

Our grey iron, Unibar 300, is alloyed to achieve the desired qualities, providing it superior wear resistance, strength, and heat-treatment response to Unibar 200 and Unibar 250 while still having an acceptable degree of machinability and a high-quality surface finish. This grade offers good dampening of noise and vibration.

Unibar 350

Unibar 350 is a special grade of alloyed material that offers high wear resistance and strength while achieving the desired qualities. All heat-treatment applications can benefit from the pearlitic structure, which responds better than Unibar 200, 250, and 300 while maintaining reasonable machinability and creating a high-quality surface finish after machining. This grade offers good dampening of noise and vibration.

Unibar 400-18LT

Our Unibar 400-18LT spheroidal iron has enhanced ductility over Unibar 400-15 and is more machinable than Unibar 400-15. It also has better low-temperature impact, fatigue, electrical conductivity, and magnetic permeability. This grade offers good dampening of noise and vibration.

  • Iron is the base metal.
  • Steel is an alloy of iron with carbon, typically less than 2%, which significantly enhances its properties.

Yes, pure iron is susceptible to rust, which is a form of corrosion. This is why iron is often alloyed with other elements to improve its corrosion resistance.

  • Unibar 200: Ideal for applications where machinability and surface finish are paramount, such as in the production of machine components and tooling.
  • Unibar 250: Suitable for a wider range of applications requiring a balance of strength, wear resistance, and machinability. Often used in the automotive and hydraulic industries.
