Most of the materials we use now are composite materials, and there is almost no single element. For example, the steel we often use is an alloy composed of iron, carbon, silicon, manganese, phosphorus, sulfur and other elements. Everyone knows that iron is white or silvery white. What subverts people's cognition is that iron is relatively soft. Is it hard to imagine that iron is soft, so pure iron cannot be used. The steel-like body we often say, hard as iron, etc., are all gone. Therefore, the steel we use in daily life is an alloy, which utilizes some characteristics of other elements, such as the hardness of carbon. Today we are talking about carbon steel square tubes, which refers to the carbon content in steel. Carbon steel generally does not have any corrosion resistance. The hardness is greater than that of pure iron. Of course, carbon is also controlled to a certain extent. Because ordinary carbon steel square tubes are not rust-proof, stainless steel carbon steel square tubes have also been developed accordingly.There are many types of stainless steel square tube materials, which refer to steel with a chromium content of greater than or equal to 13%, and alloy square tubes that are rust-proof in the atmosphere. Different stainless steels have different corrosion resistance and different corrosion resistance to different media.
Carbon steel square tube types
Carbon steel square tubes can be divided into blackened carbon steel square tubes, galvanized carbon steel square tubes, galvanized aluminum-magnesium carbon steel square tubes, and hot-dip galvanized carbon steel square tubes according to surface treatment, and the corrosion resistance gradually increases until the most corrosion-resistant hot-dip galvanized carbon steel square tubes.

What are the advantages of carbon steel square tubes?
At Yuantai Derun, carbon steel square tubes have many advantages:
1. Strength and durability
2. Low cost
3. Weldability
4. Easy processing
5. Corrosion resistance
6. Recyclable
What is the difference between carbon steel square tubes and stainless steel square tubes?
The difference between carbon steel square tubes and stainless steel square tubes is that it is generally believed that in a corrosive environment, the requirements for a smooth surface are high, and the surface is smooth and not easy to accumulate dirt. We often use stainless steel square tubes, and the deposition of dirt will cause stainless steel to rust and even cause corrosion. First of all, it is in terms of corrosion resistance. However, in practical applications, stainless steel has various excellent properties that cannot be replaced by other steel types. For example, some high-temperature resistant stainless steels, and the excellent surface properties of stainless steel are widely used in decorative materials, and the excellent mechanical properties of stainless steel make it used in various manufacturing industries. Carbon steel is relatively brittle because of its higher carbon content, but it has high hardness. For customers with needs, it is still a very good choice.
