Product Description

DIN2391 High Precision Black Phosphating Coating Steel Pipes for Hydraulic Systems

 

1.Quick Detail:

Description:High Precision Black Phosphating Coating Steel Pipes

Steel Pipes with high precision for Hydraulic Systems Black Phosphating
Standard:DIN2391

Material: St35, St45, St55, St52, St35.2, St45.2, St55.2, St52.2, etc.

2.Production process:
DIN series tubes, cold drawn and bright annealed precision seamless steel tube is used as the tube to be
phosphated.

The phosphorization is realized with the imported chemical fluid to form a black film. The antirust oil is absorbed by

means of the micropore on the film to prevent the tubes from getting rust.

3.Main Features:
Bright black color is homogeneously distributed on the tube surface. The tube has good property of antirust.

4.Main Application:
Phosphated hydraulic tube is mainly used in hydraulic system.

Delivey Condition
Designation Symbol Description
Cold finished (hard) BK Tubes do not undergo heat treatment following the final cold forming and, thus, have a rather high resistance to deformation.
Cold finished (soft) BKW The final heat treatment is followed by cold drawing involving limited deformation. Appropriate further processing allows a certain degree of cold forming (e.g. bending, expanding).
Cold finished and stress-relieved BKS Heat treatment is applied following the last cold forming process. Subject to appropriate processing conditions, the increase in the residual stresses involved enables both forming and machining to a certain degree.
Annealed GBK The last cold forming process is followed by annealing in a controlled atmosphere.
Normalized NBK The last cold forming process is followed by annealing above the upper transformation point in a controlled atmosphere.
