الخصائص الفيزيائية

Aeel plates typically have a metallic gray color with a smooth or slightly textured surface, depending on the finishing process. Surface treatments such as painting,

galppearance:

Carbon stvanizing, or powder coating can be applied to enhance appearance and provide additional protection against corrosion.

كثافة:

The density of carbon steel plates generally ranges from 7.80 to 7.85 g/cm³. For example, low-carbon steel (mild steel) has a density of approximately 7.85 g/cm³, which is slightly lower than stainless steel but higher than aluminum.

نقطة الانصهار:

The melting point of carbon steel is relatively high, typically ranging from 1425°C to 1535°C, depending on the carbon content. Low-carbon steel has a slightly higher melting point compared to high-carbon steel, making it suitable for high-temperature applications.

معامل التمدد الحراري:

The coefficient of thermal expansion for carbon steel is moderate, approximately 11.7×10⁻⁶/℃ at room temperature. This property ensures that carbon steel plates maintain dimensional stability in environments with fluctuating temperatures.

الموصلية الحرارية:

Carbon steel exhibits good thermal conductivity, with a coefficient of about 45-55 W/(m·K), which is significantly higher than that of stainless steel. This makes it an excellent choice for applications requiring efficient heat transfer.

الموصلية الكهربائية:

Carbon steel has moderate electrical conductivity, though it is lower than copper or aluminum. The electrical conductivity of carbon steel is around 10⁶ S/m, making it unsuitable for high-conductivity applications but sufficient for structural uses.

الخصائص الكيميائية

مقاومة التآكل:

Carbon steel has limited corrosion resistance compared to stainless steel. Without protective coatings, it is prone to rusting when exposed to moisture and oxygen. However, surface treatments such as galvanizing or painting can significantly improve its resistance to corrosion.

مضادات الأكسدة:

At high temperatures, carbon steel is susceptible to oxidation, especially in environments with high oxygen levels. Alloying elements like chromium or molybdenum can be added to improve oxidation resistance, but standard carbon steel requires protective measures for prolonged use in high-temperature settings.

الاستقرار الكيميائي:

In general chemical environments, carbon steel exhibits moderate chemical stability. It reacts with strong acids (e.g., hydrochloric acid, sulfuric acid) and alkalis, leading to corrosion. In neutral or mildly corrosive environments, it performs adequately, especially with protective coatings.

التخميل:

Unlike stainless steel, carbon steel does not naturally form a passive oxide layer. Instead, it relies on external treatments such as painting, galvanizing, or applying epoxy coatings to prevent corrosion. These treatments act as barriers to environmental exposure.

طلب:

Carbon steel plates are widely used across various industries due to their high strength, affordability, and ease of fabrication. In construction, they are used for structural beams, bridges, and building frameworks, providing robust support. In the automotive industry, they are used to manufacture vehicle frames and components. In the energy sector, carbon steel plates are used for pipelines, pressure vessels, and storage tanks. Additionally, in machinery manufacturing, they are employed to create gears, shafts, and other mechanical parts. Their versatility and cost-effectiveness make them indispensable in heavy industries, infrastructure development, and manufacturing.
