Parva Bright Steels is a foremost stockist and dealer of premium EN8 Bright Steel Bars (conforming to BS 970 080M40 / AISI 1045 / DIN C45 / IS 45C8) in Bhosari MIDC, Pune. EN8 is an unalloyed medium carbon engineering steel offering substantially higher tensile strength, hardness, and wear endurance compared to conventional mild steel.
Through precision cold drawing and centerless turning/peeling, our EN8 bright bars achieve tight dimensional tolerances (ISO h9, h10, h11), exceptional straightness, and a mirror-like scale-free finish. EN8 can be readily induction or flame surface-hardened to achieve 50–55 HRC, making it the preferred choice for heavy-duty shafts, automotive axles, hydraulic rams, gears, and precision turned fasteners.
Diameter: 6 mm to 100 mm
Tolerances: ISO h9 / h11
For precision motor shafts, axles, pins & CNC turned parts.
Across Flats: 10 mm to 65 mm
ISO h11 accuracy
For high-tensile nuts, bolts & hydraulic adapters.
Size: 10 mm × 10 mm to 75 mm × 75 mm
High torsional stiffness for machine keys, keyways & slides.
Band-saw cut pieces
Clean burr-free cuts to required lengths for batch production.
