Physical and Chemical Properties:

Physical Properties

Appearance:

It typically presents a metallic silver-gray color with a smooth surface after processing. Depending on the manufacturing process, it can have different finishes such as cold-rolled bright surfaces or hot-rolled oxide scales. Surface treatments like pickling or oiling are commonly applied to enhance corrosion resistance and improve appearance.

Density:

The density of SPHC carbon steel is generally around 7.85 g/cm³, which is typical for most carbon steels. This value ensures good structural strength and stability in various applications.

Melting Point:

The melting point of SPHC carbon steel is approximately 1490-1530℃. This high melting point allows it to maintain its mechanical properties even in high-temperature environments.

Coefficient of Thermal Expansion:

The coefficient of thermal expansion for SPHC carbon steel is relatively moderate, approximately 11.7×10⁻⁶/℃ at room temperature. This characteristic ensures dimensional stability during temperature fluctuations, making it suitable for industrial applications.

Thermal Conductivity:

SPHC carbon steel has moderate thermal conductivity, with a coefficient of about 50-60 W/(m·K). This property makes it suitable for heat transfer applications but less effective compared to metals like copper or aluminum.

Electrical Conductivity:

SPHC carbon steel exhibits low electrical conductivity, significantly lower than that of copper. Its resistivity is approximately 1.5×10⁻⁷ Ω·m, making it unsuitable for electrical applications but ideal for structural uses.

Chemical Properties

Corrosion Resistance:

SPHC carbon steel has limited corrosion resistance compared to stainless steel. It is prone to rust when exposed to moisture or corrosive environments. However, surface treatments such as galvanizing, painting, or oiling can significantly improve its resistance to oxidation and corrosion.

Antioxidation:

At room temperature, SPHC carbon steel exhibits moderate oxidation resistance. In high-temperature environments, it is susceptible to oxidation unless protected by coatings or alloying elements.

Chemical Stability:

SPHC carbon steel demonstrates moderate chemical stability in non-aggressive environments. However, it reacts readily with strong acids, alkalis, or other corrosive media, leading to degradation. Proper protective measures are necessary when used in chemically harsh conditions.

Passivation:

Unlike stainless steel, SPHC carbon steel does not naturally form a passive film. To enhance its corrosion resistance, surface treatments like phosphating or coating with anti-corrosion materials are applied. These treatments help prevent direct contact between the steel and corrosive agents.

Application:

SPHC carbon steel coils are widely used in various industries due to their excellent formability, weldability, and affordability. In the automotive industry, they are used to manufacture car body panels, frames, and structural components. In construction, they are utilized for roofing, wall panels, and structural supports. In the manufacturing sector, SPHC steel coils are processed into pipes, tubes, and machinery parts. Additionally, they are used in the production of home appliances, furniture, and general-purpose metal products. Their versatility and cost-effectiveness make them indispensable in many industrial applications.
