Small Diameter Precision Stainless Steel Pipe TP304 TP316L TP321 SS Pipe Tube Bright Polishing SS Pipe
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 |
