2. Main Features:
Bright black color is homogeneously distributed on the tube surface. The tube has good property of antirust.
3. Main Application:
For auto industry, machinery use, oil cylinder, motorcycle shock absorber.
4. 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.
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. Delivery Conditions:
The tubes shall be manufactured from hot finished seamless tubes by cold drawing or other suitable processes.
The tubes shall be supplied in one of the delivery conditions as follows:
| Designation | Symbol | Description |
| Cold drawn/hard | +C | No heat treatment after the final cold drawing process. |
| Cold drawn/soft | +LC | After the final heat treatment there is a suitable drawing pass. |
| Cold drawn and stress relieved | +SR | After the final cold drawing process there is a stress relief heat treatment in a controlled atmosphere. |
| Annealed | +A | After the final cold drawing process the tubes are annealed in a controlled atmosphere. |
| Normalized | +N | After the final cold drawing operation, the tubes are normalized in a controlled atmosphere. |
