Mechanical applications

4

V & M TUBES covers the full spectrum of mechanical engineering applications, from crane construction to axle manufacture, including hydraulic cylinders etc. Our broad size range and the numerous steel grades we developed allow you to find within our overall product portfolio the tube best able to meet your technical require-ments and optimize your costs.

Cranes

Design engineers are always facing new challen-ges in terms of maximum lifting capacity, lift-ing height and reach. Over the past decades, intelligent design solutions and new advanced steel grades have enabled them to continuously optimize performance. Our FineXcell® series of high-strength fine-grain steels offers an optimum combination of high yield strength, excellent impact toughness and good weldability. FineXcell® grades are often the key to success for impressive new crane performance levels.

Hydraulic cylinders

Hydraulic cylinders are found on almost all types of equipment, and are as diverse as their appli-cations. However, reducing the weight of the cylinder, or allowing for further loads is almost invariably a challenge. When the hydraulic cylin-ders are mounted on mobile equipment, each kilogram saved permits greater mobility, load bearing or lifting capacity. Grades with higher strengths and good impact energy values are typically used: our Forterior® series and FineXcell® series are the best answers for those challenges. The wide range of dimensions we supply helps our customers to minimize machining.

Mechanical applications

Oil and gas field accessories Oil & gas wells also require a wide range of mechanical engineering parts, such as downhole equipment, wellheads, and a vast range of acces-sories. High pressures and sour environment are tough conditions for equipment that has to be absolutely reliable. V & M TUBES provides a wide range of grades for those applications: our Avadur® series accepts the challenge, with good mechanical properties and hardenability, along with 13Cr grades for corrosion-resistant appli-cations.

Armatures and piling Our tubes are also used in piling and anchoring applications. Our dedicated product line, Tecnipile® comprises a selection of grades and dimensions suitable for any type of foundation.

And much more! Mechanical engineering applications cover a much wider range than the few examples ment-ioned so far! Our product series are used in roller production, for paper, textile or printing industries, in axles for truck trailers, tractors and wagons … Forterior® and FineXcell® grades are typically favoured in the design of components for con-struction equipments, such as hydraulics, steering and structural components, where they demon-strate excellent yield strength levels along with good toughness. Spirafort®, with its excellent machinability, combined with the broad range of MECAPLUS®

dimensions, ensures very low material loss during machining: the tubes are a close match to your clean-turned size, and they are easy and quick to machine!

In all cases, the main characteristics of our pro-duct families, with V & M TUBES high-quality brands, make the difference for our customers! The specific advantages of each product family, along with the most useful technical information are described in the following pages. If you have any questions regarding materials selection, please don't hesitate to contact our technicial support team.

Engineering gradesForterior®: higher strength for higher performance

Within the product family of engineering grades, the Forterior® series is the first step above standard material. Compared to basic grades, it demonstrates higher yield strength and good impact test values. With Forterior® you can reduce the weight of the structure during design, without diminishing their performance in the same operating conditions. This means less

material to purchase, but above all lighter structu-res for easy transportation, or an enhancement of performance with the same total structure weight.Such grades are typically favoured in the design of highly stressed heavy-wall hydraulic cylinders, and provide excellent strength properties, along with good toughness, with impact test values guaranteed up to –40 °C, depending on the grade.

With MECAPLUS® dimensions, we guarantee that, with a given tube, you can achieve the required dimension of your final piece, without any black spot on its surface. Additionally, tight tolerances and excellent straightness ensure that you have to remove as little material as possible during machining operations. MECAPLUS® is exclusively supplied in our Spirafort® grades, a perfect combination for machining.

This hollow bar offering is of course fully com-pliant with the requirements of the EN 10294-1, but our approach goes much further. Taking advantage of the extreme dimensional flexibility of our mills, we are now offering MECAPLUS® dimensions in a gapless size range: any outside diameter from 30 to 375 mm can now be gua-ranteed as clean-turned size, in increments of just 1 mm.

With our gapless MECAPLUS® dimensions our tube is always as close as possible to your finished dimension, so that your material loss is reduc-ed to the minimum. When machining from a solid bar, often up to 40–50 % of the material purchased is turned into scrap. By selecting the appropriate MECAPLUS® size, you can reduce this scrap to only 10 % of the material purchased.

VMec® grade series for the American market

This engineering grade family has been develo-ped with the VMec® series specially designed for our American customers. This family fills the yield strength gap between 40 ksi (Grade C) and 80 ksi (Grade 4140 Q&T) with steel grades at 50, 60 and 70 ksi. VMec®50 is fully consistent with Grade B/C of ASTM A 106 and ASME SA 106 but features higher yield strength and additional impact toughness with a restricted chemical composition for better weldability. This approach, better than standard, is a premium solution for Mechanicals. VMec®60, at the 60 ksi strength level, is available in different variants: with improved machinability, low temperature toughness or a combination of both. These steels are gene-rally weldable by all current manual and automa-tic methods. The highest grade of the family, VMec®70, features a yield strength of 70 ksi and low temperature toughness.

The FineXcell® series comprises V & M TUBES proprietary grades for fine-grain steels. FineXcell® grades offer the perfect balance between high strength, excellent toughness and resistance to brittle fracture, and excellent suit-ability for welding. It has the perfect blend of properties for the design of demanding cost-effective steel structures.

Unrivalled strength levels

Our series displays yield strengths up to an impressive 1000 MPa: the development of this grade series has opened up new fields in struc-ture design, and has, for instance, enabled crane manufacturers to achieve ever higher lifting capacities.

Additionally, there is a strong interest in reducing the dead weight of the structures without any loss of load-bearing capacity. It is a question of satisfying this demand for lightweight construc-tion while simultaneously improving the safety of highly stressed structures. This can easily be achieved with our FineXcell® series, where the use of a higher-strength tube allows you to

reduce the wall thickness and thus the weight of the tubular structure. With the same workingconditions, using FineXcell® 890 instead of simple S275 reduces weight by up to 70 % in the design of the structure. Wall thicknesses are then thinner, and thus easier to process.

Outstanding toughness at very low temperatures

However fine-grain steels do not only offer high strength. Their key characteristic is their outstanding toughness as well as their excellen-tresistance to brittle fracture. While most of the FineXcell® grades offer excellent impact test values at –40 °C, some were developed to with-stand impact tests at temperatures as low as –60 °C. FineXcell® grades are then the preferred choice for low-temperature applications, with Charpy values unrivalled by any other grade family. Additionally, the material’s excellent impact energy values ensure superior weldability, thanks to improved resistance to internal stresses.

Weldability

Being used for mechanical applications, our FineXcell® tubes of course need to be welded to other tubes or other components. Their excellent weldability is made possible by high quality pre-material with very low impurities and a stable production process resulting in a homogeneous microstructure. To ensure the good weldability of commonly quenched and tempered high-strength FineXcell® grades, relatively low carbon equiva-lents are adjusted. Depending on strength level

and application, all common manual and mecha-nised welding processes may be used. Suitable welding consumables with adequate strength levels are available from well-known suppliers of filler material.

V & M TUBES has performed weldability tests for a wide range of dimensions and strength levels of FineXcell® alloys. The data are collect-ed in a V & M TUBES database so that customers can be easily supplied with basic welding infor-mation, like heat input, pre-heating temperatures or filler material.

For more information on weldability of FineXcell® please ask for steel-grade-specific V & M TUBES wel-ding information.
