Physical and chemical properties:

Physical Properties

Density: The density of 316L stainless steel tube is approximately 7.98 g/cm³. This relatively high density gives it a certain weight, which is beneficial for applications requiring stability and strength.

Melting Point: It has a melting point in the range of 1370 – 1400 °C. This high melting point allows it to maintain its structural integrity in high – temperature environments to a certain extent.

Thermal Conductivity: The thermal conductivity of 316L stainless steel is relatively low, about 16.2 W/(m·K) at 100 °C. This property makes it a good material for applications where heat insulation is required.

Electrical Conductivity: It has relatively low electrical conductivity, which is on the order of 1.4 × 10⁶ S/m. This makes it suitable for applications where electrical insulation or controlled conductivity is needed.

Mechanical Properties: 316L stainless steel tube has good strength and toughness. Its yield strength is generally not less than 172 MPa, and its tensile strength is in the range of 485 – 655 MPa. It also has good elongation, usually not less than 40%. These mechanical properties enable it to withstand various mechanical forces and deformations without easy breakage.

Chemical Properties

Corrosion Resistance: The addition of molybdenum (Mo) in 316L stainless steel significantly enhances its corrosion resistance, especially in chloride – containing environments. It can resist the corrosion of various acids, alkalis, and salts, and has excellent resistance to pitting and crevice corrosion. This makes it widely used in harsh chemical environments, such as the marine and chemical industries.

Oxidation Resistance: At high temperatures, 316L stainless steel forms a dense oxide film on its surface, which can prevent further oxidation and maintain good oxidation resistance. It can withstand certain high – temperature oxidation environments, but continuous use at extremely high temperatures may still lead to some degree of oxidation.

Stability in Chemical Reactions: It has good chemical stability and is less likely to participate in chemical reactions under normal conditions. It can maintain its chemical properties unchanged in contact with many substances, ensuring the reliability and durability of applications in various chemical processes.

Application:

316L stainless steel tube finds extensive applications across diverse industries. In the chemical industry, it is crucial for transporting corrosive substances like acids and alkalis due to its excellent corrosion resistance. In the food and beverage sector, it is used for manufacturing pipes and equipment, ensuring hygiene and preventing contamination. In marine engineering, it is the material of choice for ship pipelines and offshore structures, withstanding seawater corrosion. In the medical field, it is employed to produce surgical instruments and hospital equipment, thanks to its biocompatibility and durability. Additionally, in architecture, it serves as decorative elements, handrails, and structural supports, combining aesthetic appeal with strength and corrosion – resistance.
