Steel plates are alloyed products of iron, and they meet the needs of different industrial scenarios through composition and process optimization. If corrosion-resistant or high-strength materials are required, stainless steel plates or special steel plates are more suitable; pure iron is mostly used in laboratories or special electromagnetic fields.
There are significant differences in composition, performance and use between steel plates and pure iron. The specific analysis is as follows:
1. Composition difference
Steel plate: An alloy formed by adding carbon (usually less than 2%) and other alloying elements (such as silicon, manganese, chromium, nickel, etc.) based on iron. According to the carbon content and added elements, it can be divided into ordinary steel, stainless steel, alloy steel and other types.
Pure iron: The carbon content is extremely low (usually less than 0.02%), and it contains almost no other alloying elements. It is soft and easy to corrode.
2. Performance difference
Mechanical properties: By adjusting the ratio of carbon and alloying elements, steel plates can have higher strength, hardness and wear resistance, while pure iron has high toughness but low strength.
Corrosion resistance: Ordinary steel plates are prone to rust, but stainless steel plates can form an anti-oxidation film because they contain chromium (such as 304 stainless steel), and their corrosion resistance is significantly better than that of pure iron.
Processing characteristics: Steel plates can be made into different thicknesses (such as medium and thick plates and thin plates) through hot rolling, cold rolling and other processes to meet the diverse needs of construction, automobiles, etc., while pure iron has fewer industrial applications.
3. Manufacturing process
Steel plates need to go through multiple processes such as blast furnace ironmaking, converter steelmaking, and rolling, while pure iron only needs to reduce iron ore and purify it.
Summary: Steel plates are alloyed products of iron, and they meet the needs of different industrial scenarios through composition and process optimization. If corrosion-resistant or high-strength materials are required, stainless steel plates or special steel plates are more suitable; pure iron is mostly used in laboratories or special electromagnetic fields.

Is the steel structure the main structure?
The core function of the main structure is to transfer loads and ensure overall safety. If the steel structure is only used for decoration or local reinforcement (such as adding a mezzanine), it does not have the function of the main structure.

Raw material composition: Molten iron is the main raw material, supplemented by scrap steel, slag-making materials (lime, fluorite, etc.) and deoxidizers (ferrosilicon, ferromanganese, etc.).

Is carbon steel plate a cold rolled plate?
The specific production process of the cold-rolled plate includes multiple rolling and annealing treatments at room temperature to obtain steel plates with a thickness of less than 4 mm. This process not only improves the surface quality and dimensional accuracy of the steel plate, but also gives it good mechanical properties and machining properties. Therefore, there are obvious differences in production process and performance between cold-rolled plates and carbon steel plates.

Difference Between Rebar and Steel Rod
The choice of rebars or steel bars should be based on project requirements. Rebars are suitable for concrete reinforcement, while steel bars are used for large steel structures that require higher bearing capacity. For more information about specific models (such as 20MnSi rebars or SNCM220 round steel), please refer to relevant standards or manufacturer data.
