STEEL GRADES The standrard stock of chromed bars consists of steel grades C45 or C45E or C45R and 20MnV6 in untreated delivery condition (+AR) and 42CrMo4 in quenched and temperd delivery condition (+QT). DELIVERY CONDITIONS The solid bars subjected to chroming process are available in different delivery conditions in orde to obtain specific properties. NORMALIZATION Heat treatment consisting heating process followed by gradual cooling in controlled atmosphere. Thanks to this process the steel structure becomes more "refined" and improve its impact properties (perlitic structure). INDUCTION HARDENING The surface of the steel bar is heated by electric induction followed by fast cooling. This process leads to a high surface hardness but also to fragility and low impact values (Martensite surface structure). QUENCHING AND TEMPERING Quenching process followed by tempering. This process leads to a good hardness and resistance and it reduces its fragility in comparsion to induction...

Production standards are summarized as below for Cold Formed Sections; Water and gas pipes: EN 10217-1 TR1, EN 10255, DIN 2440, BS 1187, ISO 65, N FA49-145, ASTM A53, ASTM A500, DIN 2999-2986, BS 1387, ASTM A53 Industrial Pipes: DIN 2458-1615 & 1626, BS 6363, BS 6323, BS 1139, EN 39, EN 10219-2 Open Sections: EN 10162 Square and Rectangular HS: EN 10219-2, DIN 2395, DIN 59411, BS 6363, N FA49-541, ASTM A500, UNE 36-537, SI 1458 For Hot Formed Sections as per EN 10210/ASTM A501.

We supply the pipes that are suitable for bending and are used for the constructions of plants and equipment subject to high temperatures and pressures. The seamless pipes, hot rolled or cold drawn/cold finished with heat treatment. The ASTM A335/ASME SA335 and EN 10216-2 norms require heat treatment also for the hot rolled pipes. The welded pipes are manufactured according to EN 10217-2. Supply of pipes suitable for high temperatures are according to; ASTM A 106 / ASME SA 106 (Seamless pipes) ASTM A 335 / ASME SA 335 (Seamless pipes) EN 10216-2 (Seamless pipes) EN 10217-2 (Welded pipes)

We can supply pipes for the construction of pipelines, equipment and tanks subject to low temperatures as Seamless or welded pipes, hot rolled or cold finished. Pipe norms suitable for low temperatures are according to; ASTM A 333 / ASME SA 333 (seamless and welded pipes) EN 10216-4 (Seamless pipes) EN 10217-4 (Welded pipes)

As per the norm EN 10297 specifies the technical delivery conditions for seamless round steel tubes. The tubes for mechanical applications are mainly used in those processes in which turning and CNC machines are used. The wide size range available, with OD from 21.3 to 812 mm, gives the possibility to manufacture several kinds of components for different applications: small machine parts, flanges, fittings, Archimedean screws, hydraulic cylinders for heavy machines etc.

The round SEAMLESS tubes are hot rolled and satisfy both the requirements of the norm EN 10210 for structural applications and EN 10297-1 for mechanical applications. These steel tubes are fully killed and are suitable for structural applications but with the possibility to reach up to 100 mm w.t., which is impossible for welded tubes. These tubes are used for the manufacture of various kinds of construction components, above all where heavy wall thickness are required. EN 10210-1/2 (structural applications) EN 10297-1 (mechanical applications)

The round tubes are manufactured from a coil that is bent and electric resistance welded (ERW). The forming process can be according to EN 10210, which foresees hot forming or cold forming followed by heat treatment, or according to EN 10219, which foresees cold forming without following heat treatments. The finished product is fully killed and welding seam bead is inside and outside trimmed. These products are used to manufacture both welded and bolted structures, in the field of constructions, engineering, industrial constructions, transports, automotive, agricultural machinery and earth moving machinery. The cold finished tubes are particularly suitable for structures at sight or for aesthetical uses, thanks to the surface aspect typical of cold forming.

The different kinds of cold drawn tubes ready on stock cover a wide range of applications: COLD DRAWN SEAMLESS AND WELDED TUBES SUITABLE FOR HONING. COLD DRAWN SEAMLESS AND WELDED TUBES INSIDE H8. COLD DRAWN SEAMLESS TUBES FOR SHAFTS. WELDED SMOOTH BORE CYLINDER TUBES INSIDE H9 OR H10. COLD DRAWN SEAMLESS TUBES FOR HYDRAULIC AND PNEUMATIC POWER SYSTEMS. Seamless and Welded Cold Drawn pipes honed or ready for honing; H8, H9 or H10. STEELGRADES AND DELIVERY CONDITIONS COLD DRAWN / HARD (+C acc. EN 10305 / BK acc. DIN 2391) No heat treatment after final cold drawing. COLD DRAWN / SOFT (+LC acc. EN 10305 / BKW acc. DIN 2391) The final heat treatment is followed by a suitable drawing pass (limited reduction of area). STRESS RELIEVED (+SR acc. EN 10305 / BK+S acc. DIN 2391) After the final cold drawing process, tubes are stress relieved in controlled atmosphere in order to reduce work hardening due to the cold forming process. ANNEALED (+A acc.
