Compared with the surface obtained by ordinary annealing and pickling, the chromium-depleted surface of the strip is reduced due to the absence of the oxidation process, and the corrosion resistance is better than that of the 2B plate after polishing.
Stainless Steel BA Coil
Huaxiao of Stainless Steel BA Finish Coil
As a supplier of stainless steel coils, we export stainless steel ba finish coils of various materials, specifications, and surfaces. We have exported ordinary stainless steel coils of common materials for 14 years. in fact, stainless steel ba finish is bright annealed stainless steel, we can also call it ba stainless steel coil.
The material we export most is 304 ba stainless steel coil, 430 ba stainless steel.
In recent years, in order to meet the diversified needs of customers, we have gradually expanded our product range and improved product quality. We accept customized product sizes, as well as colorful stainless steel coils. For more products, please refer to our Brochures.
If you need stainless steel ba finish coil or other stainless steel coils, please free to contact me.
We currently have a large inventory of bright annealed stainless steel.
You can see our inventory of stainless steel ba finish coil in the picture below. If you need it for the test, we can provide samples of stainless steel ba finish for your reference. Looking forward to your inquiry of stainless steel ba finish coil.
Description of bright annealed stainless steel coil, stainless steel ba finish
- BA surface is a special finish, like mirror finish but not bright enough to mirror.
- Bright annealing also be called brilliant annealing, is to anneal the products in a confined space slowly cooling at least 500 degrees, then make the products natural cooling still in the enclosed space, after that to get the brightness and beautiful surface, and without causing decarburization situation.
Purpose and advantage of Stainless Steel BA Finish Coil Processing
- 1, To eliminate work hardening, to obtain a satisfactory metallographic structure. When the use of different performance requirements, the microstructure of the bright annealed after the request is different, the bright heat treatment process is also different.
- 2, Access to the non-oxide bright, good corrosion resistance of the surface. Since bright annealing heats the product surface under a protective atmosphere of a mixture of hydrogen and nitrogen, a non-oxidized and bright surface is obtained by strictly controlling the atmosphere in the furnace, in particular, purity, residual oxygen, and dew point.
- Compared with the surface obtained by ordinary annealing and pickling, the chromium-depleted surface of the strip is reduced due to the absence of the oxidation process, and the corrosion resistance is better than that of the 2B plate after polishing.
- 3, The bright processing Maintains the finish of the rolling surface, can no longer be processed to obtain a shiny surface. Due to the bright annealing, the coil or sheet surface retains its original metallic luster and has been obtained with a shiny surface close to the mirror surface, it can be used directly without another machining, for general requirements.
- 4, Can make a special rolling pattern surface strip or coil. As the annealing process, there is no change in the surface of the steel, the surface can be completely retained the pattern, you can easily design a special cold-rolled strip or coil.
- 5, there is no pollution caused by the ordinary pickling method. After annealing the strip does not require pickling or similar treatment, do not use a variety of chemical substances such as acids, there are no pollution problems caused by pickling.
- 6, To achieve the control of the stainless steel coil straightness. Because the design of the bright annealing furnace allows sub-section adjustment along the width of the strip or coil, the online control of the sheet can be realized by adjusting the cooling rate in the width direction of the strip by the airflow diversion.
Bright Annealing Process for Bright Annealed Stainless Steel
1: Material of bright annealed stainless steel is a collective term for the materials that are annealed in a bright annealing furnace after rolling of stainless steel. The advantage of this kind of bright annealing furnace is to use a protective atmosphere for protection, which can prevent the surface of the material from being oxidized.
For example, our common BA surface is This way of handling.
2: Others such as 2B surface, it is heated by air or gas furnace for solution treatment, the surface will be oxidized after treatment, so it needs to be pickled after treatment to remove.
