Physical properties and chemical properties:

Physical properties

Appearance:

Usually long strips, with a right triangle cross section, two perpendicular sides, and a generally smooth surface, but there may be some traces left during the rolling process, and the color is mostly silver-gray.

Density:

The density of carbon steel angle is about 7.85g/cm³, which makes it much heavier than some metals with lower density such as aluminum at the same volume.

Melting point:

The melting point of general carbon steel is around 1450-1500℃, and the specific value will vary slightly depending on the content of carbon and other impurity elements in carbon steel.

Electrical conductivity and thermal conductivity:

It has good electrical conductivity and thermal conductivity, and can conduct current and heat well, but its electrical and thermal conductivity are not as good as metals such as copper and aluminum.

Magnetic properties:

At room temperature, carbon steel angles are usually ferromagnetic and can be attracted by magnets.

Chemical properties

Corrosion resistance:

Carbon steel angles easily react with oxygen, water, etc. in the air to rust, and its main component, iron, will be oxidized into iron oxide. In a humid environment, the rusting speed will accelerate. If it is in an environment containing corrosive media such as acids, alkalis, and salts, the corrosion rate of carbon steel angles will increase significantly.

Oxidation:

At high temperatures or in a specific oxidizing atmosphere, the iron element on the surface of carbon steel angles is easily oxidized to form iron oxides of different valence states. For example, when heated to a certain temperature in air, black ferroferric oxide or red ferric oxide will be generated.

Reaction with acids:

Carbon steel angles can react chemically with a variety of acids. For example, reaction with hydrochloric acid will generate ferrous chloride and hydrogen, and reaction with sulfuric acid will generate ferrous sulfate and hydrogen. If the acid concentration is high or the reaction conditions are more intense, the reaction rate will be accelerated, and some other side reactions may be accompanied.

Reaction with alkali:

Under normal circumstances, the reaction of carbon steel angles with alkali is relatively slow. However, under some special conditions, such as high temperature, concentrated alkali solution, etc., some components in carbon steel may react with alkali, but this reaction is relatively less common.

Weldability:

Carbon steel angle steel has good weldability. During the welding process, the steel is heated to the melting point and fuses with the welding rod or wire to form a strong welded joint. However, it is necessary to pay attention to controlling the welding parameters during the welding process to avoid welding defects such as pores and cracks. At the same time, appropriate heat treatment may be required after welding to improve the performance of the welded joint.

Application:

Carbon steel angles are widely used in many fields. In the construction industry, it is a key material for building house frames, steel structure factories and bridges. It can withstand large loads and ensure structural stability. It is also commonly used to make decorative components such as door and window frames and stair handrails. In the field of mechanical manufacturing, it can be used as equipment brackets and mechanical frames to provide stable support for various types of machinery. In power engineering, carbon steel angles are used to construct transmission towers and substation structures to ensure the safe operation of power facilities. In addition, it is also used to manufacture daily necessities such as hardware shelves, fences, ladders, etc. It also plays an important role in scenes such as shipbuilding and agricultural greenhouse construction. With its good mechanical properties and economy, it has become a common material in industrial and civil fields.
