Rock Drill Piston












APPLICATION

Rock Drill Piston

SECTOR
  • Oil & Gas
  • Mining
GRADE
  • Unibar 600
  • Unibar 700
  • Unibar-600-3 & Unibar-700-2 – possible to be austempered to achieve higher strengths and hardness equivalent to case hardened EN8 steel
  • Unibar ADI
SUITABLE TO REPLACE
  • Steel
  • Steel Forging
ADVANTAGES
  • Good vibrational absorption – quieter running
  • Lighter than steel
  • Better machinability – self lubricating – chip generating
  • Higher wear resistance
  • Higher tensile strength
  • Better surface finish
  • Shorter deburring time
  • No shrinkage or porosity
COST SAVING
  • Extended tool life due to self lubricating properties
  • Weight reduction
