BENTELER Steel/Tube has succeeded in producing seamless tubes from free-cutting steel for the first time with BENTELER SMARTCUT®. It combines the advantages of highly machinable free-cutting steels with the geometry advantages of a tube and thus optimizes machining. The product line of seamless steel tubes in hot-rolled as well as cold-drawn types offers optimized solutions for various applications. In this way, economical machining can be realized both for smaller quantities and for large-scale series production.
Due to the production of the steel in an electric arc furnace, a reduction of the CO2 footprint by more than 70 percent can be achieved with BENTELER SMARTCUT® compared to bar steel from the blast furnace route. In addition, the tubes are guaranteed lead-free in accordance with the EU REACH Regulation to protect the environment.
With cooperation from steel distribution partners and customers, BENTELER Steel/Tube provides application-specific, seamless tube solutions for machining companies, machine builders and manufacturers of precision workpieces with BENTELER SMARTCUT®.
“Our customers use free-cutting steel tubes to manufacture rotationally symmetrical turned parts and individual special shapes according to drawings, including sleeves, components and spacer rings for electric motors. They appreciate the excellent machinability of our free-cutting steel tubes. In close cooperation with our customers, we develop customized solutions: In this process, the material properties of the free-cutting steel can be individually adapted to the application. Additional heat treatments ensure high strength combined with good formability. In addition, the tubes can be supplied with customized finishes, such as a machined inner surface or as a pre-cut short length. This means there is an optimum solution for every application,” emphasizes Bernd Mehren, Head of Engineering for seamless hot-rolled tubes.
With SMARTCUT®, BENTELER Steel/Tube is using the class of free-cutting steels for the first time for a product family of specific tube solutions. The use of these tubes made of free-cutting steel allows significant productivity increases to be achieved in the machining industry.

“Excessively long, uncontrolled chip formation leads to increased susceptibility to faults, scrap and tool wear on our customers’ equipment. Due to its material properties, BENTELER SMARTCUT® offers greatly improved, short chip formation. This has a positive effect on tool life, which is up to four times longer with BENTELER SMARTCUT® tubes. In addition, the material concept enables faster machining and, as a result of the stable process, also automated machining, which can reduce machining costs by up to 40% in total. This not only pleases the commercial management when considering the operating costs, but also has a positive effect on the ability to plan the production process,” says Mr. Jan Schwarzer, Director Sales, summarizing the advantages.
