Cold Drawn 17mm High Precision Steel Tube ST52 DIN2391 Tube Seamless Pipe

TORICH is a rich-experienced manufacturer of steel tube especially for precision DIN2391, EN103051, etc steel tube.

1.Brief introduction of cold drawn high precision steel tubes of DIN2391:

OD:16-325mm WT:1-22mm

Material:ST35, ST45,ST52, ST30 Si, ST30Al

Our testing:

dimensional check,

surface inspection,

tensile test

flattening test

drift expanding test

Length tolerance:

up to 500mm: +2mm/-0mm

above 500mm up to 2000mm: +3mm/-0mm

above 2000mm up to 5000mm: +5mm/-0mm

length above 5000 up to 7000mm: +10mm/0mm

Tube ends:

Cold darwn high precision steel tube shall be cut nominally square to the tube axis and shall be free from excessive burrs.

Quantity ordered in meters:

up to 500: +20% deviation

above 500 up to 2000: +15% deviation

above 2000: +10% deviation

2.Final supply conditions:

BK (+C) Cold finished/hard (cold finished as drawn) No heat treatment after the last cold forming process.
BKW (+LC) Cold finished/soft (lightly cold worked)

After the last heat treatment there is a light finishing pass (cold drawing).

BKS (+SR) Cold finished/stress relieve annealed. After the final cold forming process the tubes are stress relieve annealed.
GBK (+A) Annealed After the final cold forming process the tubes are annealed in a controlled atmosphere
NBK (+N) Normalized. (Mainly focus on) After the final cold forming process the tubes are annealed above the upper transformation point in a controlled atmosphere
