⚙️ 24 mm steel round bar - pulleys, flanges, and heavy-duty shafts

24 mm steel round bar is hot-rolled long product used as stock for large rotating parts. At over 3.5 kg per metre, it is a blank that can be faced into pulleys, flywheels, and flanged hubs, or turned lengthwise into heavy-duty shafts. Grades 20 and 45 structural steel are available for demanding machining applications.

🏗️ Main applications:

  • Pulleys and flywheels: large-diameter blanks for face turning.
  • Flanges and hubs: support components for connections and rotating assemblies.
  • Heavy-duty shafts: loaded drive shafts made from grade 45 steel.
  • Kingpins and machinery axles: heavy-duty pins for trailers and attachments.

Frequently asked questions

How much does 1 metre of 24 mm round bar weigh? +
According to the ДСТУ 4738 range, the theoretical weight of 1 linear metre of 24 mm steel round bar is 3.551 kg - approximately 282 metres per tonne. A 6 m bar weighs about 21.3 kg.
How does 24 mm round bar differ from 25 mm - are they not the same size? +
No, they are two different stocked sizes. A 1 mm difference in diameter changes the weight (3.551 compared with 3.850 kg/m) and, more importantly, the machining allowance for the finished part. Check the drawing before ordering: use 24 mm bar for a finished size of 23 mm, but a finished 24 mm part requires 25 mm bar.
Which 24 mm round bar grade is suitable for a pulley or flange? +
Grade 20 steel is sufficient for pulleys, flywheels, and flanges under moderate loads. For parts subject to wear and high torque, choose grade 45 steel with hardening. Ст3 is used for welded hubs and supports. We select the grade according to the part's function.
