Round Bar EN8/EN19/EN24

High-tensile alloy and medium-carbon Engineering Round Bars (EN8, EN19, EN24) engineered for heavy-duty power transmission, high-stress shafting, and precision mechanical components.

Applications:

  • EN8 (080M40) Applications Medium-tensile shafts, axles, gears, studs, bolts, keys, and stress-bearing mechanical components.

  • EN19 (708M40 / 4140) Applications High-tensile drive shafts, crankshafts, connecting rods, high-stress gears, and oilfield drilling tools.

  • EN24 (817M40 / 4340) Applications Ultra-high strength power transmission gears, heavy-duty marine shafts, aircraft structural parts, and power plant components.

  • Precision Machining & Tooling High-specification turned parts, hydraulics, heavy vehicle axles, and forged engineering components.

Engineering Steel Round Bars in EN8, EN19, and EN24 grades are high-strength carbon and alloy steel sections specially designed to perform under severe torsional, impact, and wear conditions. Offering superior hardenability, tensile strength, and fatigue resistance, these engineering-grade round bars are essential for components requiring post-machining heat treatment such as quenching, tempering, or surface induction hardening.

Sourced from accredited global steel mills and held in stock at our Sajja yard, our engineering round bars strictly conform to BS 970 and international equivalents (such as AISI 1045, 4140, and 4340). Delivered with complete EN 10204 3.1 Mill Test Certificates (MTC), they are available as EN8 (medium carbon for general engineering), EN19 (high-tensile oil-hardening alloy steel), and EN24 (nickel-chromium-molybdenum alloy for ultra-high stress applications)—supplied in standard lengths with custom saw-cutting and surface conditioning options.
