Filiz Steel, based in Istanbul, Turkey, stands out as a top manufacturer and supplier of EN10305-1 and EN10305-4 Seamless Tubing. They provide high-precision steel tubes tailored for automotive, hydraulic, and industrial uses. These seamless tubes are crafted to offer remarkable strength, precise dimensions, and a smooth surface finish, making them ideal for critical applications. Filiz Steel guarantees that its EN10305 tubing adheres to European standards, ensuring dependable mechanical properties, consistent wall thickness, and excellent corrosion resistance. With state-of-the-art production facilities and strict quality control measures, the company delivers seamless tubes that perform reliably even in the toughest industrial environments around the globe.
The EN10305-1 / EN10305-4 Seamless Tubing is made from top-notch carbon and alloy steels, with a carefully controlled chemical composition to ensure outstanding mechanical properties. EN10305-1 tubes are generally drawn tubes suitable for cold working and various applications, providing solid tensile strength, yield strength, and ductility. On the other hand, EN10305-4 tubes are cold-drawn, stress-relieved, and precision-engineered for hydraulic and high-pressure applications, offering exceptional dimensional accuracy, surface quality, and fatigue resistance. Both types are designed to maintain weldability and machinability, making them easy to work with in demanding situations.
