The physical and chemical properties of carbon steel channel steel:

Physical properties:

1. Density:

about 7.85 g/cm3, which makes it have a larger mass under the same volume, increasing the stability of the structure.

2. Elastic Modulus:

has a high elastic modulus, when the force is relatively small deformation, can better maintain the shape and size of the structure.

3. Thermal Expansion Coefficient:

the thermal expansion coefficient is large, the size change is more significant when the temperature changes, this factor needs to be taken into account in the design and application.

4. Magnetic:

most carbon steel channel steel has magnetic properties, which makes it used in some applications that require magnetic properties, such as electromagnetic equipment.

5. Gloss:

the surface can show a certain luster after treatment, but not as bright as materials such as stainless steel.

Chemical properties:

1. Reaction with oxygen:

At room temperature, the surface will gradually oxidize with oxygen to form an oxide film, but in humid and high-temperature environments, the oxidation rate increases.

2. Reaction with acid:

It is easy to react and dissolve with strong acids such as hydrochloric acid and sulfuric acid to produce hydrogen and corresponding salt compounds.

3. Reaction with base:

Under certain conditions, it can react with strong bases, especially in high temperature and strong alkaline environments.

4. Electrochemical corrosion:

In the electrolyte solution, it is easy to form a primary battery, electrochemical corrosion occurs, resulting in damage to the material.

5. Alloying:

Alloying can be achieved by adding other elements, thus altering its chemical properties and properties to meet specific requirements.
