Физические свойства

Появление:

Carbon steel angle steel usually presents a metallic gray color, with a surface that can be smooth or slightly rough depending on the manufacturing process. Different surface treatments, such as painting, galvanizing, or powder coating, can be applied to enhance its appearance and corrosion resistance.

Плотность:

The density of carbon steel angle steel is generally around 7.85g/cm³, which is slightly lower than stainless steel but higher than many other construction materials. For example, Q235 carbon steel, a commonly used grade, has a density of approximately 7.85g/cm³.

Температура плавления:

The melting point of carbon steel angle steel is relatively high, typically in the range of 1425-1540℃. This makes it suitable for applications in environments where structural stability at elevated temperatures is required.

Коэффициент теплового расширения:

The coefficient of thermal expansion is moderate. In the range of room temperature to 100℃, the coefficient of thermal expansion for carbon steel is about 11.7×10⁻⁶/℃. This property ensures good dimensional stability under varying temperature conditions.

Теплопроводность:

Carbon steel has relatively good thermal conductivity compared to stainless steel, with a thermal conductivity coefficient of approximately 50-60W/(m·K). This makes it suitable for applications requiring heat transfer.

Электропроводность:

Carbon steel has moderate electrical conductivity, but it is not primarily used for electrical applications. The conductivity of carbon steel is significantly lower than copper but sufficient for grounding or structural uses.

Химические свойства

Коррозионная стойкость:

Carbon steel angle steel has limited corrosion resistance compared to stainless steel. Without protective coatings, it is prone to rust when exposed to moisture or corrosive environments. However, treatments like galvanizing or painting can significantly improve its resistance to corrosion. For example, hot-dip galvanized carbon steel is widely used in outdoor structures due to its enhanced durability.

Антиоксидантное действие:

Carbon steel has moderate oxidation resistance at room temperature, but at higher temperatures, it is susceptible to oxidation. Alloying elements such as chromium or molybdenum can be added to improve its oxidation resistance in high-temperature applications.

Химическая стабильность:

In general chemical environments, carbon steel angle steel exhibits moderate chemical stability. It may react with strong acids, alkalis, or other aggressive chemicals, leading to corrosion. Protective coatings are often applied to mitigate these effects in harsh environments.

Пассивация:

Unlike stainless steel, carbon steel does not naturally form a passivation film. Instead, surface treatments such as galvanizing, painting, or applying protective coatings are used to prevent corrosion. These treatments create a barrier between the steel surface and the environment, extending the material’s lifespan.

Приложение:

Carbon steel angle steel is widely used in various industries due to its excellent strength, affordability, and ease of fabrication. In construction, it is commonly used for structural frameworks, support beams, and reinforcement in buildings and bridges. In industrial applications, it serves as a key component in machinery frames, equipment supports, and conveyor systems. It is also used in infrastructure projects, such as railway tracks, transmission towers, and pipelines. Additionally, in the manufacturing sector, carbon steel angle steel is utilized to produce tools, automotive components, and storage racks. Despite its susceptibility to corrosion, proper surface treatments ensure its long-term performance in demanding environments.
