Machinery Steel

Machinery steels are carbon steels suitable for the working parts of the machine in general mechanical engineering industry. Different grades of steel can be applied to components with different level of stress and pressure ranging from moderate to high.All our machinery steel materials are hardened and tempered for oil quenching and water quenching. It is also suitable for flame hardening and induction hardening.

General Applications:-
  • Axles
  • gears
  • shafts
  • pins
  • fasteners
  • hand tools
  • short run punching and cutting tools
  • base plates for mould and die
  • simple moulds
  • hydrogenation vessels
  • pinions
  • arbours
  • connecting rods
  • tool joints and drill collars (oil & gas industry)
  • crankshafts
  • driving gears
  • eccentric shafts
  • steering components
