DIN17175 12CrMo AISI4140 4130 1045 Precision Seamless Steel Hydraulic Cylinder Pipe and Tube
Description
Hydraulic tube is made according to DIN 2391/C (DIN EN 10305-1) or DIN 2445/2 (DIN EN 10305-4) standards and it is available in millimeters, inches outer diameter, and inches nominal bore size.
manufacturing process of seamless hydraulic tubing
Seamless hydraulic tubing is produced as a seamless tube by rolling and piercing bar stock.
It then gets multiple cold-drawing reductions before a final cold draw guarantees tight dimensional tolerances and excellent surface finish. After final sizing of the tube through cold drawing it undergoes intermediate annealing and a dead-soft annealing process.
The tubes surface finishing is NBK, where the tubes are phosphate and normalized which provides corrosion resistance. It is oiled inside and outside. Normalize process creates tougher metal product. During normalizing, metals will be heated at a high temperature, and it allowed to naturally cool back down to room temperature by exposure after heating. Metals that have been through this process are more formable, harder and ductile.
