DIN2391 EN10305-1 E235 E355 Carbon Shock Absorber Tube 10x1 12x1

1.Quick Detail:
Black Phosphated Hydraulic Tubes with High Precision
EN10305-1, EN10305-4, DIN2391,
E235, E355, ST37.0, ST44.0, ST52.0
Steel Pipes with high precision for Hydraulic Systems Black Phosphating

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:
For auto industry, machinery use, oil cylinder, motorcycle shock absorber

5.Our products are widely used in:
Engineering machinery Machine tool industry Hydraulic industry Special vehicle
Automobile pipeline Heavy machinery Compressor Shipbuilding industry
Railway locomotive Diesel engine Utility boiler Injection molding machine
Power equipment Heavy duty automobile Forging and stamping machine

6.Main Characteristics:
No Oxidation Layer on the Outer and Inner Walls
No Crack under Flaring and Flattening
No Leakage under High Pressure
No Distortion after Cold Bending
High Precision High Cleanness Excellent Brightness

7. Delivery condition:

The tubes can be produced in the following delivery 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
