Rolled bar<\/h6>\n\t\t\t\t\t

The right round size, in the right grade<\/h2>\n\t\t
\n \t\t\t

Rolled bar<\/strong>, also known as rolled steel<\/strong> or round bar, is the obvious choice when a standard round size suffices. We supply it to buyers and workshops that machine shafts, bushings, and pins themselves. You receive the grade, standard, and delivery condition you specify, with the corresponding certificate and a single point of contact from inquiry to delivery.<\/p>\n\t\t\n<\/div>\n

From rough rolled to fully machined<\/h2>\n\t\t
\n
\n \t\t\t

Rough rolled<\/h3>\n\t\t\t\t\t

Delivered as the bar comes out of the mill, with mill scale and the dimensional tolerances of the standard. This is useful when you saw the material to length and turn it on your own machines.<\/p>\n\t\t\n<\/div>\n

\n \t\t\t

Rough turned<\/h3>\n\t\t\t\t\t

Turned to a clean, inspected outer diameter without mill scale, enabling ultrasonic testing. You can then immediately start the final machining in your own workshop or machine factory.<\/p>\n\t\t\n<\/div>\n

\n \t\t\t

Fully machined<\/h3>\n\t\t\t\t\t

We deliver the bar as a finished component according to your drawing, for example as a shaft, bushing, or pin, with dimensional inspection and material certificate. Ready for assembly in your construction.<\/p>\n\t\t\n<\/div>\n\n<\/div>\n\n<\/div>\n

Process<\/h6>\n\t\t\t\t\t

How rolled bar is created<\/h2>\n\t\t\t\t\t

A cast ingot or billet enters a furnace until it reaches rolling temperature and is then passed through a series of rolling stands. Each pair of rollers reduces the cross-section slightly until the round final size is reached. After cooling, the bar is straightened, sawed to length, and inspected. Where necessary, heat treatment, rough turning, and machining according to drawing follow.<\/p>\n\t\t\n<\/div>\n\t\t\t\"Gewalst\t\t\n<\/div>\n

What is rolled steel or rolled bar?<\/p>\n\t\t\n<\/span>\n

\n \t\t\t

Rolled bar<\/strong> is round bar material that gets its shape by repeatedly passing a heated billet between rotating rollers. Because the rolling profiles determine the cross-section, it is available in fixed round sizes. In the trade, it is also called rolled steel, round bar, or rolled bar stock. It is the common starting form for turned parts that you machine further yourself.<\/p>\n\t\t\n<\/div>\n\n<\/details>\n

\n \n \n \t\t\t

When do I choose rolled bar and when forged bar?<\/p>\n\t\t\n<\/span>\n

\n \t\t\t
<\/path><\/svg><\/div>\n\t\t\n<\/div>\n\n<\/summary>\n
\n \t\t\t

Choose rolled bar<\/strong> if a standard round size suffices and you machine the material further yourself. Forged bar<\/a> is the better choice for larger diameters, heavy unit weights, or a stepped shape from one piece, such as a forged shaft<\/a>. Open-die forging is also the obvious choice for high requirements on the internal quality of large cross-sections. We advise per inquiry which form fits best technically and commercially.<\/p>\n\t\t\n<\/div>\n\n<\/details>\n

What is the difference between hot-rolled and cold-rolled steel?<\/p>\n\t\t\n<\/span>\n

\n \t\t\t
<\/path><\/svg><\/div>\n\t\t\n<\/div>\n\n<\/summary>\n
\n \t\t\t

Hot-rolled steel<\/strong> is rolled above the recrystallization temperature, cold-rolled steel without that heating. Hot rolling allows for large deformations and thick cross-sections, with mill scale on the surface and wider tolerances. Cold finishing gives a smoother surface, tighter dimensions, and higher strength through work hardening. Round bar according to EN 10060 is hot-rolled. Which execution fits depends on the dimensional accuracy required for your final machining.<\/p>\n\t\t\n<\/div>\n\n<\/details>\n

\n \n \n \t\t\t

Up to what diameter do you supply rolled bar?<\/p>\n\t\t\n<\/span>\n

\n \t\t\t
<\/path><\/svg><\/div>\n\t\t\n<\/div>\n\n<\/summary>\n
\n \t\t\t

We supply rolled bar in diameters up to 300 mm<\/strong>. If you need a larger cross-section, we switch to forged bar, which we supply with diameters up to 5,000 mm and unit lengths up to 26 meters. This way, you keep the same point of contact for small and large round sizes, with the same agreements on certification, inspection, and delivery.<\/p>\n\t\t\n<\/div>\n\n<\/details>\n

What dimensional tolerances apply to hot-rolled round bar?<\/p>\n\t\t\n<\/span>\n

\n \t\t\t
<\/path><\/svg><\/div>\n\t\t\n<\/div>\n\n<\/summary>\n
\n \t\t\t

For hot-rolled round steel for general applications, the tolerances from EN 10060<\/strong> apply. That standard regulates the permitted deviation in diameter, length, straightness, and ovality, in dimensional tables up to 250 mm. If you want a tighter tolerance or a guaranteed size for your final machining, we supply the bar rough turned. You then receive a controlled outer diameter that can be further machined directly on your own machines.<\/p>\n\t\t\n<\/div>\n\n<\/details>\n

\n \t\t\t

Rolled bar is available in a wide range of steel grades, from unalloyed structural steel<\/strong> and quenched and tempered steel such as 42CrMo4<\/a> to stainless grades. We determine which combination of grade and diameter is feasible per inquiry. Our stock program<\/a> shows which grades we can provide. If your grade is not listed, feel free to ask.<\/p>\n\t\t\n<\/div>\n\n<\/details>\n

Do you supply rolled bar rough, rough turned, or fully machined?<\/p>\n\t\t\n<\/span>\n

\n \t\t\t
<\/path><\/svg><\/div>\n\t\t\n<\/div>\n\n<\/summary>\n
\n \t\t\t

Yes, you choose which of the three executions<\/strong> you need. Rough rolled is the most economical choice if you saw and turn it yourself. You choose rough turned when ultrasonic testing is required or when you want a reliable starting dimension. Fully machined is useful if you have no in-house machining capacity or want to receive the component with a single certificate and dimensional report.<\/p>\n\t\t\n<\/div>\n\n<\/details>\n

Is rolled bar delivered heat-treated?<\/p>\n\t\t\n<\/span>\n

\n \t\t\t
<\/path><\/svg><\/div>\n\t\t\n<\/div>\n\n<\/summary>\n
\n \t\t\t

That depends on the delivery condition<\/strong> you order. Common conditions include quenched and tempered (+QT) for strength and toughness, and soft annealed (+A) for good machinability. The heat treatment meets at least the standard of the grade; a customer-specific treatment is possible upon request. The condition is stated on the certificate.<\/p>\n\t\t\n<\/div>\n\n<\/details>\n

\n \t\t\t

You receive a certificate according to EN 10204<\/strong> with rolled bar; depending on your requirement, that is type 2.2, 3.1, or 3.2. The document states the chemical composition and the mechanical properties of the heat. If an independent inspection is required, we arrange it through our quality assurance<\/a>, for example with T\u00dcV or DNV as the inspecting authority. Each piece remains traceable to the original heat.<\/p>\n\t\t\n<\/div>\n\n<\/details>\n

\n \t\t\t

For a number of grades and round sizes, rolled bar is sometimes available from stock<\/strong> on short notice. If the material must first be rolled, rough turned, or machined, the lead time depends on the grade, diameter, and length. A rough turned execution is in some cases available within 6 working weeks, a fully machined part usually within 8 to 10 working weeks. We state a concrete delivery date in the quote.<\/p>\n\t\t\n<\/div>\n\n<\/details>\n\n<\/div>\n
