Forging Quality Steels

Forging Quality Steels are widely used in automobile, defence, railways and various manufacturing industries. Automobile industry is the single largest user of forgings. Components produced through forging are generally used in the transmission systems of an automobile where large forces get transferred between different parts,
hence they are of vital importance.

Quality requirements for Forging Quality Steels

  • Close control on chemistry
  • Freedom from harmful internal and surface defects
  • Dimentional tolerance IS 3739 grade ‘I
  • High degree of cleanliness
  • Fine and Uniform Grain Size

These steels are widely used in automobile, defence, railways and various manufacturing industries.
