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.

Typical Forging Quality Steel Grades
Bearing steels are special class of low alloy steels, typically with 1% carbon and 1.4% chromium. Manganese and Molybdenum are added in certain special cases.
