Product Q&A

Q:Is EN 10305 the same as EN 10305-1?

No. EN 10305 is a multi-part series. Part 1 specifically covers seamless cold-drawn tubes for precision applications.

Q:What is the confirmed factory size range?

The confirmed range is 15-70 mm outside diameter and 1-14 mm wall thickness. Specific combinations depend on grade, condition and tolerance.

Q:Can DIN 2391 still be ordered?

DIN 2391 is a withdrawn legacy reference. Old drawings can be reviewed, but the current specification and all technical requirements must be confirmed before supply.

Q:Which delivery conditions are available?

+C, +LC, +SR, +A and +N can be reviewed. Availability depends on grade, size, required properties and the ordered standard.

Q:Can the tubes be supplied as machined parts?

Yes, cutting, chamfering, drilling, threading, CNC turning, honing and other operations can be reviewed against the drawing.
