EN10305-1 E235-N Low Carbon Steel Tube Cold Drawn For Precision Applications
Standard EN 10305 covers steel precision tubes. The standard includes delivery conditions for six different parts. Part 1 or EN 10305-1 refers to seamless cold drawn precision tubes. These precision tubes are specially marked with the letter E, so they are manufactured to standards and hold tight tolerances, making them ideal for use as machine parts. This is because the precision steel tube en 10305-1 is the same as the system to be connected.
EN10305-1, E235+N seamless pipe
EN 10305 is suitable for seamless precision steel tube
applications.
Power Steering Applications
The EN 10305 European Standard specifies the technical delivery
conditions for seamless cold-drawn pipes of circular cross-section
for hydraulic and pneumatic systems.
Standard and Steel Grades:
EN10305-1 E215
EN10305-1 E235
EN10305-1 E355
The allowable pressure rates and temperatures are the
responsibility of the customer according to the ety factors
specified in the latest technical and application regulations,
codes or standards.
Pipes complying with this EN 10305 European standard are characterized by precisely defined dimensional tolerances and specified surface roughness.
EN 10305 Seamless precision tubes shall be cold drawn from hot worked seamless tubes. Other suitable cold working methods are permitted. The tube shall be delivered in delivery condition +N, which means that after the final cold drawing operation, the tube is normalized in a controlled atmosphere.
NBK refers to protective heat treatment in a non-oxidizing environment to make the surface of the pipe bright and smooth.
