CS Heavy Forgings manufactures EN8 and EN9 forged shafts, rods and engineered components to customer drawings for industrial machinery, rolling mills, gear systems and general engineering equipment.
EN8 and EN9 are carbon engineering steels requested where buyers need a practical balance of strength, machinability, hardness and cost. EN9 has a higher carbon level than EN8 and may be selected where the specification calls for greater hardness or wear resistance after heat treatment. Final properties depend on section size, processing and the governing material standard.
Review the broader steel grades for heavy forgings guide before comparing material families. Final selection remains the responsibility of the purchaser or component designer and must follow the complete drawing and specification.

Frequently asked questions
What is the difference between EN8 and EN9 for forged shafts?
EN9 generally contains more carbon than EN8 and may achieve greater hardness and wear resistance after suitable heat treatment. The correct choice must follow the drawing, material standard, loading and required mechanical properties.
Can EN8 and EN9 shafts be supplied machined?
Enquiries can specify as-forged, heat-treated, rough-machined or finished-machined supply, subject to drawing review, dimensions, tolerances and inspection requirements.
