APPLICATION

Bevel Gear

SECTOR
  • Various – Automobile and Agricultural Machine Manufacture
  • Machinery and Machine Tools Manufacture
  • Textiles
GRADE
  • Unibar 300
  • Unibar 500
  • Unibar 600
  • Unibar 700
  • Unibar ADI
  • Unibar-600-3 & Unibar-700-2 – possible for these grades to be austempered to achieve higher strengths and hardness equivalent to case hardened EN8 steel
SUITABLE TO REPLACE
  • Steel
  • Sand Castings
ADVANTAGES
  • Better machinability – self lubricating – chip generating
  • Higher wear resistance
  • Higher tensile strength
  • Better surface finish
  • Shorter deburring time
  • Good vibrational absorption – quieter running
  • No shrinkage or porosity
  • Lighter than steel
  • Finer grain structure than sand castings
COST SAVING
  • No pattern costs
  • No rejected parts
  • Scrap reduction
  • Extended tool life because of no sand inclusions and self lubricating properties
  • Smaller machining allowance
