Beauty 304 Stainless Steel Seamless Pipes Used in Construction Industry
Architects have always chosen stainless steel to construct cost-effective permanent buildings. Many existing buildings fully illustrate the correctness of this choice. Some are very ornamental, such as the Chrysler Building in New York City. But in many other applications, the role of stainless steel is not so compelling, but it plays an important role in the aesthetics and performance of the building. For example, because stainless steel has more wear resistance and indentation resistance than other metal materials of the same thickness, it is the material of choice for designers when building sidewalks in places with high population flows.

3. Surface:
| No.4 | It has good gloss and fine lines on the surface. Processing technology: Polishing and tempering rolling of 2D products or 2B with 150 ~ 180 abrasive material (JIS R6002). |
| HL | It is silver-gray with hair streaks. Processing technology: Polish the 2D product or 2B product with a suitable size of abrasive material to make the surface appear continuous grain. |
| 8K | It is in a mirror state. Processing technology: 2D or 2B products are ground and polished to a mirror effect with a suitable abrasive material. |
| 2B | It is silvery white and better gloss and flatness than 2D surface. Processing technology: hot rolling + annealing shot peening pickling+ cold rolling + annealing pickling + quenching and tempering rolling. |
| BA | The surface gloss is excellent and has a high reflectivity, just like the mirror surface. Processing technology: hot rolling +annealing shot peening pickling + cold rolling + annealing pickling + surface polishing + quenched and tempered rolling. |
| 1D | surface has discontinuous particles, also known as matte. Processing technology: hot rolling + annealing shot peening pickling +cold rolling + annealing pickling. |
| 2D | It is slightly shiny silvery white. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing
pickling. |
| No.3 | has better gloss and rough surface. Processing technology: Polishing and tempering rolling of 2D products or 2B with 100 ~ 120
abrasive materials (JIS R6002). |
| SB | The surface is smooth, the texture is clear, the texture is delicate, the appearance is comfortable, and the taste is high-grade.It is widely praised by consumers especially in kitchen appliances. |
