Physical and chemical properties of carbon steel H-beams:

1. Physical properties:

(1) Shape and structure:

The carbon steel H-beam has an “H” shape and is composed of upper and lower flanges and middle webs. This structural design allows it to effectively distribute stress when subjected to vertical and horizontal forces, and has good mechanical properties. Its cross-section shape is regular, making it easy to connect and combine.

(2) Density and mass:

The density is about 7.85g/cm ³, which is heavier. This allows it to provide stable support in applications such as construction and machinery.

(3) Strength and hardness:

It has high strength and can withstand greater pressure, tension and shear forces. Its hardness is also considerable, depending on the specific composition of carbon steel and heat treatment methods. It can be used for structures that withstand heavy loads.

(4) Toughness and ductility:

It has a certain degree of toughness and will not break easily when subjected to impact loading.

(5) Thermal and electrical conductivity:

It is a good conductor of heat and electricity.

(6) Melting point and thermal expansion coefficient:

The melting point is high, between 1370 and 1530 ° C. The thermal expansion coefficient is relatively small, and the dimensional change is relatively stable when the temperature changes, which is conducive to maintaining the accuracy and stability of the structure.

2. Chemical properties:

Reaction with other chemical substances:

In an acidic environment, the carbon steel H-beam will chemically react to produce hydrogen and generate a corresponding iron salt solution. It can also react with some metal salt solutions. For example, in a copper sulfate solution, iron will replace copper, forming copper elements on the surface of the beam, and at the same time convert itself into a ferrous sulfate solution.

Product application:

1. Construction engineering field:

It is a key structural material for building high-rise buildings, bridges and other large buildings. Its high strength and good bearing capacity can effectively support the weight of the building and ensure the stability and safety of the building structure. In the construction of industrial plants, carbon steel H beams can be used to build spacious space frames to meet the needs of production equipment installation and cargo storage.

2. Machinery manufacturing industry:

Carbon steel H-beams are often used to make the bases and frames of large machinery and equipment. It provides a solid and reliable foundation for the operation of equipment and can withstand various forces and vibrations generated during the operation of equipment.

3. Rail transit construction:

Carbon steel H-beams can be used in structural construction. Its stable performance can adapt to the environment of dense personnel and complex equipment, ensuring the normal operation of rail transit facilities.

4. Power facilities construction:

Carbon steel H-beams can be used for the structure of substations, transmission towers, etc. It can withstand the erosion of natural environments such as wind and rain, and ensure the safety and stability of power transmission.
