What is 1.4301 2B steel plate?
1.4301 is a common type of stainless steel, also known as AISI 304, that has good corrosion resistance and formability. The "2B" refers to its surface finish, which is a bright, smooth, and slightly matte appearance achieved through a specific cold-rolling and heat treatment process. This finish makes it a versatile material for applications like kitchen equipment, architectural decoration, and chemical processing.
1.4301 2d vs 1.4301 2b stainless steel sheet
What is the difference between 2B and 1.4301 2D finish stainless steel plate ?
The main difference is that 2B is a brighter and more reflective finish than 2D because it undergoes an extra "skin pass" rolling step with polished rollers. 2B is the most common cold-rolled finish, while 2D is a duller, matte finish that is often the base for 2B and other finishes.
| Feature | 2B Finish | 2D Finish |
|---|---|---|
| Appearance | Moderately dull, but smooth and reflective | Dull, matte, and gray |
| Manufacturing Process | Cold-rolled, annealed, pickled, and then "skin passed" (light rolled) with polished rollers | Cold-rolled, annealed, and pickled |
| Surface Smoothness | Smoother due to the final skin pass | Rougher than 2B |
| Reflectivity | More reflective | Less reflective |
| Common Use | The most common finish for general purposes, and a base for other polished or brushed finishes | Used for applications where a highly reflective surface is not required |
What is the difference between 2B finish and No.1/No.4 finish?
2B finish is cold-rolled and pickled with a smooth, uniform matte surface. No.1 is hot-rolled with a rougher finish, suitable for industrial fabrication, while No.4 is brushed for decorative or aesthetic purposes.
