EN8 Steel Billets
EN8 (080M40) medium carbon steel. General-purpose medium carbon steel with a good balance of strength and machinability. It responds to quenching and tempering in small and medium sections.

EN8 billets and blooms
EN8 billets and blooms are among the most requested sizes for forging shops and machining of shafts and studs.
Kesari Alloys supplies EN8 as continuous cast billets and blooms from 100 × 100 to 250 × 250 mm and 200 mm round, in lengths up to 12 metres. See the billet size chart for weight per metre.
Heat treatment: Normalised, or hardened and tempered. Hardenability is limited, so it suits smaller sections.
Typical uses of EN8
- Shafts and axles
- Gears and sprockets
- Studs, bolts and couplings
- General engineering forgings
Industries: forging, re-rolling mills, sugar mill shafts and rollers, railway components, fasteners and bolts.
