High Precision Bright Annealed(BA) Stainless Steel Tubing For Instrumentation

To reduce hardness and improve plasticity; bright annealing stainless steel can also refine the grain and eliminate the internal stress, annealing must be carried out. It can well protect the bright outer surface of the stainless steel tube, and at the same time, the stainless steel tube does not need pickling after annealing after brightening.

In the production process of stainless steel pipe, the grease grain used for lubrication may be deformed due to production and processing. In order to avoid the residual grease in the stainless steel tube as much as possible, the annealing process is reasonably high temperature, and the furnace atmosphere is argon. The combination of argon and carbon-oxygen on the surface of the stainless steel tube combustion, further cleaning the surface of the stainless steel tube, forming a bright effect. This method of heating a smooth surface with pure argon and rapidly cooling it is called bright annealing.

The surface of the stainless steel tube can be kept clean in this way, free from any external pollution. However, if the brightness of this surface is compared with other polishing methods such as mechanical, chemical, and electrolysis, it will have a matte feel. Of course, its effect is also related to the content of argon and the number of heating times.

Applicable industries: biopharmaceutical, electronic clean workshop, high purity gas, high demand clean laboratory, liquid crystal display, solar photovoltaic, polycrystalline silicon, and other fields.
