• Detailed Description:

  Quantity: 10Metric Tons
  Price:950 USD Metric Tons
  Applications
  Alloyed case hardening steel for parts with a required core tensile strength of 800 – 1100 N/mm² and good wearing resistance as piston bolts, camshafts, levers and other vehicle and mechanical engineering components. Higher stressed components – gears, shafts, crankshafts, connecting rods, cam shafts, etc.

  Features
  • Calcium treated steel for Inclusion modification
  • Contains soft, deformable calcium aluminates encapsulated in manganese sulphide rather than hard alumina oxide inclusions
  • Tightly controlled hardenability
  • Controlled analysis for repeatable strength and fatigue properties
  • Grain size 5 or finer

  Benefit
  The modified inclusions are less abrasive to cutting tools, acting as a lubricant and barrier at the tool /workpiece interface.Compared with the standard grade the IM steel gives:
  • Improved machinability with reduced machining cost
  • Up to 30% longer tool life for a given cutting speed
  • Up to 20% higher cutting speeds for a given tool life
