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 |
