Propiedades físicas

Apariencia:

It usually presents a silvery white metallic color, with a smooth surface and high gloss. Different surface effects can be obtained through different surface treatment processes, such as mirror polishing, brushing, etc. Stainless steel angle bars are often used in structural applications where their aesthetic appeal and corrosion resistance are highly valued.

Densidad:

The density is generally between 7.93-8.00g/cm³. For example, the density of the commonly used 304 stainless steel angle bar is about 7.93g/cm³, and the density of the 316 stainless steel angle bar is about 7.98g/cm³, which is slightly higher than ordinary carbon steel.

Punto de fusión:

El punto de fusión es relativamente alto, generalmente entre 1398 y 1454 °C. Por ejemplo, el punto de fusión del acero inoxidable 304 es de aproximadamente 1400 a 1450 °C, lo que le confiere una buena estabilidad en entornos de alta temperatura.

Coeficiente de expansión térmica:

The coefficient of thermal expansion is relatively small. In the range of room temperature to 100℃, the coefficient of thermal expansion of 304 stainless steel is about 17.2×10⁻⁶/℃. This feature enables stainless steel angle bars to maintain good dimensional stability in an environment with large temperature changes.

Conductividad térmica:

La conductividad térmica es pobre y su coeficiente de conductividad térmica es de aproximadamente 16 – 27 W/(m・K), que es mucho más bajo que el del cobre, aluminio y otros metales, por lo que tiene cierto rendimiento de aislamiento térmico.

Conductividad eléctrica:

Tiene cierta conductividad eléctrica, pero es relativamente baja. La conductividad del acero inoxidable 304 es de aproximadamente 1,4 × 10⁶ S/m, que equivale tan solo a un 41 TP3T de la conductividad del cobre.

Propiedades químicas

Resistencia a la corrosión:

This is one of the most important chemical properties of stainless steel angle bars. Because a dense passivation film can be formed on its surface, this passivation film can prevent oxygen, water, etc. from contacting the metal matrix, thereby effectively preventing corrosion. For example, 304 stainless steel angle bars have good corrosion resistance in environments such as atmosphere, water and weak acids and alkalis; 316 stainless steel angle bars contain molybdenum, which is more resistant to chloride ion corrosion and are often used in marine environments or chemical environments that are exposed to chloride ions.

Antioxidación:

Stainless steel angle bars have good oxidation resistance at both room temperature and higher temperatures. For example, 310S stainless steel angle bars can withstand high temperatures in high temperature environments without being easily oxidized, and can be used in high temperature furnace structures and other occasions.

Estabilidad química:

In general chemical media, stainless steel angle bars have high chemical stability and are not easy to react chemically with common chemicals. However, in some specific strong corrosive media, such as concentrated nitric acid, hydrofluoric acid, etc., the corrosion resistance of stainless steel angle bars may be affected.

Pasivación:

After the stainless steel angle bar is in the air or after passivation treatment, a passivation film will form on the surface. This passivation film can improve the corrosion resistance and oxidation resistance of stainless steel. Passivation treatment usually involves immersing the stainless steel angle bar in a solution containing an oxidant, such as nitric acid, potassium dichromate, etc., to promote the formation and repair of the passivation film.

Solicitud:

Stainless steel angle bars are widely used in many fields due to their excellent corrosion resistance, high strength and good processing performance. In the field of construction, they are used to manufacture structural supports, frames, and reinforcements, ensuring durability and aesthetic appeal. In building decoration, they are often used for window frames, door frames, handrails, and artistic sculptures, combining beauty with long service life. In mechanical manufacturing, they can be used as structural components in equipment frames, machine bases, and support systems to ensure stable operation of machinery. In the food processing industry, stainless steel angle bars are used to construct equipment frames, conveyor systems, and storage racks, meeting strict hygiene standards. In addition, in the fields of chemical equipment, electronic appliances, etc., stainless steel angle bars are also indispensable. They are used to manufacture structural supports for reactors, frames for valves, and housings for electronic equipment, adapting well to complex working environments.
