EN 10297-1 E355 honed tubes are high-strength carbon steel seamless tubes, manufactured according to EN 10297-1 standard. They are cold-drawn and precision honed (or SRB finished) to achieve tight dimensional tolerances, ultra-smooth inner surfaces, and high fatigue resistance. These tubes are ideal for hydraulic cylinders, pneumatic actuators, lifting equipment, and heavy-duty machinery.
