4 Mechanical applications 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 requirements and optimize your costs. Cranes Design engineers are always facing new challenges in terms of maximum lifting capacity, lifting 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 applications. However, reducing the weight of the cylinder, or allowing for further loads is almost invariably a challenge. When the hydraulic cylinders 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. 4

5 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 accessories. 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 applications. Armatures and piling Our tubes are also used in piling and anchoring applications.

7 Engineering grades Forterior : 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 structures 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.

14 FineXcell Top of the range for extreme performance 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 costeffective steel structures. Potential weight savings for construction high-strength fine-grain steels compared Potential to S275 weight savings for construction high-strength fine-grain steels compared to S % Unrivalled strength levels 50% tension / compression Our series displays yield strengths up to an impressive 1000 MPa: the development of this grade series has opened up new fields in structure design, and has, for instance, enabled crane manufacturers to achieve ever higher lifting capacities. 0% S275 FineXcell 360 FineXcell 460 FineXcell 700 FineXcell 780 FineXcell 800 FineXcell 900 bending FineXcell 960 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 construction 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 working conditions, 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 excellentresistance to brittle fracture. While most of the FineXcell grades offer excellent impact test values at 40 C, some were developed to withstand 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. 14

Their excellent weldability is made possible by high quality prematerial 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 equivalents are adjusted. Depending on strength level and application, all common manual and mechanised 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 collected in a V & M TUBES database so that customers can be easily supplied with basic welding information, like heat input, pre-heating temperatures or filler material.
