Thickness and Width:
The thickness and width of stainless steel an vary according to specific needs and applications. Generally speaking, the thickness of stainless steel can range from a very thin few millimeters to tens of millimeters, and the width is usually between tens of millimeters and several meters.
We can provide different specifications and sizes of stainless steel, and can choose the appropriate thickness and width according to the specific needs.
Hot Rolled and Cold Rolled
Stainless steel products can be manufactured using either hot rolled or cold rolled techniques. Hot rolling involves heating the steel above its recrystallization temperature and then passing it through rollers to form the desired shape. Cold rolling, on the other hand, involves passing the steel through rollers at room temperature to reduce its thickness.
Different Finishes
Stainless steel comes in different finishes that can affect its appearance and properties. Here are some common finishes:
| Different Finishes |
| 2B: This is a smooth, reflective finish that is produced by cold rolling followed by annealing and descaling. |
| No.1: This is a rough, dull finish that is produced by hot rolling followed by annealing and pickling. |
| SB: This is a satin finish that is produced by applying a fine abrasive material to the surface of the steel. |
| BA: This is a bright, mirror-like finish that is produced by buffing the surface of the steel with a fine abrasive material. |
| HL: This is a hairline finish that is produced by brushing the surface of the steel with a fine abrasive material. |
| Mirror: This is a highly reflective finish that is produced by polishing the surface of the steel with a very fine abrasive material. |
