High precision cold drawn welded steel tubes are essential for precision machinery equipment, offering exceptional dimensional accuracy and strength. These tubes undergo a meticulous cold drawing process, enhancing their mechanical properties and surface finish. Their welds are expertly crafted to ensure durability and reliability under high stress. Ideal for applications requiring tight tolerances, they provide excellent performance in various industries. With resistance to corrosion and fatigue, these tubes are vital for enhancing the efficiency and longevity of precision machinery.

• +C: No heat treatment after the final cold drawing process
• +LC: After the final heat treatment there is a suitable drawing pass
• +SR: After the final cold drawing process there is a stress relieve heat treatment in a controlled atmosphere
• +A: After the final cold drawing process the tubes are annealed in a controlled atmosphere
• +N: After the final cold drawing operation the tubes are normalized in a controlled atmosphere
