Filiz Steel, a prominent supplier located in Istanbul, Turkey, specializes in high-quality **EN 10305-2 and EN 10305-3 ERW tubing** designed for applications that demand precise dimensional tolerances, a superior surface finish, and dependable mechanical properties. These electric resistance welded (ERW) tubes are crafted according to European standards that govern steel tubes for precision uses. EN 10305-2 pertains to cold-drawn welded tubes, while EN 10305-3 focuses on welded tubes in various delivery conditions, including as-welded, normalized, or cold-formed. Filiz Steel provides these tubes in a range of diameters, wall thicknesses, and steel grades to fulfill specific customer needs for both structural and mechanical applications.
The EN 10305-2 tubing is produced from cold-drawn low carbon steel, ensuring tight dimensional tolerances and smooth internal and external surfaces, making it perfect for applications that require machining or hydraulic forming. In contrast, EN 10305-3 tubing is made from hot-rolled or cold-rolled strip and is generally used in less demanding scenarios. The mechanical properties can differ based on the steel grade, but typical minimum yield strengths range from 235 MPa to over 500 MPa, depending on the processing and material choices. These tubes come with various surface treatments, such as oiled, pickled, or phosphate-coated, to accommodate different end-use environments.
