Small Diameter Precision Stainless Steel Pipe TP304 TP316L TP321 SS
Pipe Tube Bright Polishing SS Pipe
Stainless steel is an alloy of Iron with a minimum of 10.5%
Chromium. Chromium produces a thin layer of oxide on the surface of
the steel known as the passive layer. This prevents any further
corrosion of the surface. Increasing the amount of Chromium gives
an increased resistance to corrosion.Stainless steel also contains
varying amounts of Carbon, Silicon and Manganese. Other elements
such as Nickel and Molybdenum may be added to impart other useful
properties such as enhanced formability and increased corrosion
resistance.

Surface Finishing of our stainless steel pipe
| Surface | Description |
| Plug Draw | The surface roughness is improved by precise cold drawing of the
plug, which can improve the surface structure |
| Mechanically Polished | Surface roughness enhanced by precision grinding |
| Pickled & Passivated | Pickled or passivated to remove particles remaining on the surface |
| Buffed Polished | use polishing paste to improve surface brightness, often used in
decoration industry |
| Bright Annealing | Use high temperature heat treatment in a vacuum state to form a
passivation film on the surface |
| Anodical Cleaning | On the basis of BA, add a mild electrolytic polishing process and
thicken the passivation film |
| Electro-Polished | Through electrochemical polishing, the surface has a closed and
thick chromium oxide film |
