Comparison of Cold Rolled Low Carbon Steel Plate and Pure Iron


This article aims to compare cold rolled low carbon steel plate and pure iron, exploring their differences and applications in various industries. The comparison will be conducted from four aspects: mechanical properties, corrosion resistance, formability, and cost. By delving into these aspects, readers will gain a comprehensive understanding of the characteristics and advantages of each material. This knowledge will contribute to informed decision-making when selecting the appropriate material for a specific application.

1. Mechanical Properties

The mechanical properties of cold rolled low carbon steel plate and pure iron play a vital role in determining their performance in various applications. Cold rolled low carbon steel plate, also known as mild steel, offers excellent strength, durability, and impact resistance. It is widely used in automotive manufacturing, construction, and general engineering applications. On the other hand, pure iron possesses exceptional toughness and magnetic properties, making it suitable for industries such as electrical engineering and magnet manufacturing. Understanding the differences in their mechanical properties is essential for choosing the right material for specific purposes.

2. Corrosion Resistance

Corrosion resistance is a critical factor when considering the suitability of materials for certain environments. Cold rolled low carbon steel plate is prone to rusting when exposed to moisture and corrosive substances. To mitigate this, various surface treatments and coatings are employed. In contrast, pure iron exhibits poor resistance to corrosion. However, in certain applications where corrosion resistance is not a significant concern, pure iron's unique properties can be advantageous. By comparing the corrosion resistance of these two materials, engineers and designers can make informed decisions according to the intended use and operating conditions.

3. Formability

Formability refers to the ease with which a material can be manipulated into desired shapes. Cold rolled low carbon steel plate offers excellent formability, making it suitable for applications that require complex shapes, such as sheet metal fabrication and structural components. Pure iron, although less malleable than low carbon steel, still exhibits reasonable formability, particularly in applications where its unique properties are sought after. By understanding the formability characteristics of these materials, manufacturers can optimize their production processes and achieve desired outcomes effectively.

4. Cost

Cost is a significant consideration in material selection. Cold rolled low carbon steel plate is generally more economical compared to pure iron. The widespread availability and ease of production contribute to its lower cost. Pure iron, being less common and requiring specialized production processes, tends to be more expensive. However, the unique properties of pure iron may justify the additional cost in specific applications. Evaluating the cost differences between these materials enables decision-makers to balance performance requirements with budget constraints.


In conclusion, the comparison of cold rolled low carbon steel plate and pure iron has highlighted their differences in terms of mechanical properties, corrosion resistance, formability, and cost. Each material offers unique advantages and disadvantages that should be taken into consideration when selecting the appropriate material for an application. By understanding these differences, engineers, designers, and manufacturers can make informed decisions to optimize product performance and reduce costs. Further research and development in this field would enable the exploration of innovative materials and applications, leading to advancements in various industries.
