5 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 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 cylindersHydraulic cylinders are found on almost all types of equipment, and are as diverse as their appli-cations.

6 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 applicationsOil 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.

7 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.

8 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 & M tubes offers the full product portfolio for mechanical engineering , from basic grades to the most advanced proprietary fine-grain steels.

9 You can be sure that when we offer basic carbon grades, our tubes are not basic tubes ! When choosing V & M tubes , you will benefit from our high-quality production, based on a decades of know-how of seamless steel tube manufactu-ring. In Europe, the most popular carbon steel grades for mechanical engineering are the E355 (confor-ming to EN 10297-1) and the S355J2H (confor-ming to EN 10210). We also have our Multicert series, which complies with both EN 10297 and EN 10210. Multicert is a product line dedicated to our distributors, in order to optimize their materialCarbon steel grades1) AR: as rolled ; N: normalized or normalizing formed; QT: quenched and tempered. 2) values apply for the lowest wall thickness range defined in V & M tubes materials datasheets.
