Physical and chemical properties:

1. Physical properties

Density: The density of stainless steel channel steel is usually between 7.7 and 8.0g/cm³, such as the density of 304 stainless steel channel steel is about 7.93g/cm³. This makes it of great reference value in weight calculation and structural load-bearing design. In architectural and mechanical structural applications, the impact of its own weight on the overall structure needs to be considered.

Strength

Tensile strength: With high tensile strength, the tensile strength of 304 stainless steel channel steel is generally above 500MPa. This enables it to withstand large tensile forces and play a role in application scenarios such as beam and column structures of buildings and tensile parts of machinery.

Yield strength: The yield strength is usually greater than 200MPa, which ensures that plastic deformation will not easily occur under a certain pressure, which helps to maintain the safety and stability of the structure.

Hardness: The Rockwell hardness (HRC) is generally around 70-90, with good wear resistance, and is more suitable for some occasions that need to resist friction and wear, such as in applications such as rails of conveying equipment, which can reduce wear.

Thermal conductivity: The thermal conductivity is relatively low, about 12 – 30W/(m·K), which makes it have certain thermal insulation properties in high temperature environments. In the support structure of some high-temperature equipment, it can effectively reduce the transfer of heat and protect the surrounding components.

Ductility: It has good ductility and can be formed by rolling, bending and other processing methods, which is convenient for manufacturing various shapes of structural parts to meet different architectural and mechanical design requirements.

2. Chemical properties

Corrosion resistance: Due to the presence of chromium, chromium forms a dense protective film of chromium oxide (Cr₂O₃) on its surface. It has good corrosion resistance in general environments such as atmosphere and fresh water. 316 stainless steel channel steel has stronger corrosion resistance in environments containing chloride ions (such as seawater) and highly corrosive chemical media because it contains molybdenum.

Antioxidation: It can maintain good anti-oxidation properties in high temperature environments. Within a certain temperature range, the protective film on the surface can prevent oxygen from further oxidizing the internal metal, thereby playing a role in applications such as support structures for high-temperature equipment.

Chemical stability: It is relatively stable in general chemical environments and will not react violently with common chemicals (such as organic acids in food and some mild chemical reagents in chemical production). Therefore, it is widely used in the fields of food processing equipment frames and chemical equipment brackets.

Application:

Stainless steel channel steel is widely used. In construction projects, it can be used to build frame structures for industrial plants and warehouses. Its corrosion resistance makes the buildings durable in complex environments and has a neat and beautiful appearance. In bridge construction, it serves as an auxiliary support structure to enhance the stability and bearing capacity of the bridge. In the field of mechanical manufacturing, it is an ideal material for equipment bases and frames, and can withstand the vibration and pressure generated by mechanical operation. In municipal facilities, such as installation brackets for bus stops and street light poles, it relies on its sturdiness and weather resistance to ensure the normal use of facilities for a long time.
