Topson Group Provides Quality Stainless Steel Decorative Sheets Gobally.
No.1 Finish Stainless Steel
The surface of hot-rolled stainless steel comes in 5 grades. No.1 is the primary surface finish, which results from hot rolling to the specified thickness, followed by annealing and descaling. With sheets/coils/strips types, No. 1 finish stainless steel is characterized by its rough, dull, and non-uniform appearance. It is generally used in industrial applications where the surface finish is not critical, such as chemical tanks, piping, heat exchangers, equipment for elevated temperature service, and checker plates.
Manufacturing process:
At first, stainless steel is heated and then rolled at a high temperature to achieve the desired thickness. Secondly, the hot-rolled steel is annealed in a controlled atmosphere to relieve internal stresses and achieve a uniform microstructure. At last, the surface is descaled to remove the oxide layer that forms during annealing.
Standard Sizes
Sheets/Plates: 1000mm*2000mm, 1219mm*2438mm, 1219mm*3048mm, 1500mm*3000mm
Coils: prime materials. 1000mm*C, 1219mm*C, etc.
Available Size
No.1 finish stainless steel results from hot rolling to the specified thickness, followed by annealing and descaling. A customized specific cut-to-width is acceptable, but the fee will be high. Its rough surface provides good resistance to wear and tear, making it suitable for heavy-duty applications. The available thickness ranges from 4.00 to 12.00mm. If your thickness is over this scope, please consult us for an assessment.

Application
As the unique surface of the hot-rolled stainless steel, No.1 finish is a rough, dull surface compared to the more polished finishes. Generally, No.1 finish stainless steel is suitable for applications that do not require a smooth or reflective surface. Therefore, it is commonly used in industrial or structural uses where cost-effectiveness is more important than aesthetics. If you are a stainless steel manufacturer, No.1 finish stainless steel can also be a base material for further processing or finishing.

No.1 Finish Stainless Steel VS 2B finish stainless steel
● No.1 finish stainless steel belongs to hot rolled stainless steel, suitable for applications with low surface requirements. 2B finish stainless steel is achieved by cold-rolling and light polishing, making it more suitable for applications requiring a better appearance.
● No.1 stainless steel finish is rougher and duller, while the 2B finish is smoother and slightly reflective.
● No.1 finish stainless steel is ideal for functional, industrial, and structural applications, while 2B finish stainless steel is better suited for decorative, architectural, and consumer-oriented uses.
● In terms of hardness, 2B finish stainless steel may be slightly harder, and No.1 stainless steel is slightly softer.
● Regarding ductility, the ductility of No.1 stainless steel is lower than that of 2b finish stainless steel. However, No.1 stainless steel is stronger than 2b finish stainless steel.
Stainless steel sheets are commonly used in an office reception area or architectural decoration design. It's not enough to be simply durable. Therefore, colored stainless steel is gradually being recognized. Do you know how colored stainless steel produced? Deposition, also called PCVD, includes physical vapor deposition(PVD) and chemical vapor deposition(CVD). The production process of colored stainless steel is PVD coating, which uses physical methods to heat or excite a Ti material process and deposit a thin film.
