Their seamless tubing finds extensive use in hydraulic, automotive, mechanical, and structural applications, catering to both local and international markets with dependable solutions.
EN 10305-1 seamless tubes are cold-drawn precision tubes featuring smooth surfaces and tight dimensional tolerances, made from low-carbon steel that boasts excellent machinability and weldability. On the other hand, EN 10305-4 seamless tubes are tailored for hydraulic and pneumatic applications, providing high cleanliness, uniformity, and impressive pressure resistance. The mechanical properties of these grades include tensile strength ranging from 340 to 520 MPa, yield strength between 235 and 355 MPa, and elongation of 20 to 30%. Their composition, primarily iron with controlled amounts of carbon, manganese, and silicon, strikes a perfect balance between strength, ductility, and fatigue resistance.
