The difference between stainless steel and cold-rolled steel is very big. The maximum thickness of common cold-rolled steel is 8mm. Hot-rolled steel coils are generally used as raw materials to produce beautiful and easy-to-use cold-rolled steel. Each coil can reach 13.5 tons. Stainless steel is different. Stainless steel has no specified thickness, and its raw materials are generally not limited to steel, but also include nickel, chromium, and molybdenum, all of which are metals. Stainless steel has certain corrosion resistance, and ordinary chemical properties will not cause it to corrode.
What is the difference between cold rolled steel and stainless steel：
1. Different properties: Stainless steel is resistant to weak corrosion such as air and water. It is also called stainless acid-resistant steel. Cold-rolled steel is mainly made from hot-rolled coils as raw materials, which are rolled at room temperature after crystallization.
2. Different types of steel: Cold-rolled steel is produced into a kind of steel after cold rolling. And stainless steel is a relatively common one, also called 18/8 stainless steel.
3. Different directions of use: cold-rolled steel is suitable for use in construction, while stainless steel is suitable for food processing and transportation.
Stainless steel: beautiful surface and diversified use possibilities. Good corrosion resistance and longer durability than ordinary steel. Good corrosion resistance and high strength, so the possibility of using thin plates is high. Resistant to high temperature oxidation and high strength, so it can resist fire and be processed at room temperature, that is, it is easy to process. Plastic processing does not require surface treatment, so it is simple, easy to maintain and clean, and has high smoothness and good welding performance.
How to choose stainless steel plate：
1. Distinguish the material
There are many types of stainless steel plates. Generally speaking, they can be divided into 201, 304, 316, etc. It can be said that these are all processed and colored. Relatively speaking, 316 has the best corrosion resistance, 201 is worse, and the price is different. It is also large. When purchasing, you need to identify the materials to avoid being deceived by the merchants.
2. Surface coloring process
The surface of stainless steel has been treated with different colors. Different treatment methods are used, and the price difference is also relatively large. The more common one is water plating coloring process, and the other is vacuum plating coloring.
3. Observe the metal surface
If it is colored, then a layer of metallic color will be applied to its surface. It can be said that its decorative effect is good. During the purchase process, you should also check the surface to see if there is any color difference. Also check Are there any scratches or blisters?
4. The quality of the film
If it is a colored stainless steel plate, its surface is usually covered with a layer of protective film. This surface will be smoother. When choosing, you should check whether the quality of the film is good. If it is easy to tear off, it means that it is easy to tear off. The quality of this film is very poor, which will also affect the use effect.
