Product Description

EN 10305-4 Standard Steel Pipe for hydraulic and pneumatic power systems

The steelmaking process of EN10305-4 is at the discretion of the manufacturer and steels shall be fully killed. The tubes shall be manufactured from hot finished seamless tubes by cold drawing. Other suitable methods of cold working are permitted. The tubes shall be delivered in the delivery condition +N which means that after the final cold drawing operation the tubes are normalized in a controlled atmosphere.
