Price List Of High Quality 201 304l 304 Stainless Steel Pipe

304l stainless steel sheet has a maximum carbon content of 0.030%, similar in properties to 304 stainless steel sheet but with higher performance in the sensitized range. Due to its excellent resistance to intergranular corrosion after stress relief or welding, 304l stainless steel has a wider range of applications. An ultra-low carbon version of 304l stainless steel is required when welding heavy sections or when an aggressive corrosive environment is present and post-weld annealing is not possible. 304l stainless steel can become sensitive if exposed to operating temperatures of 800℉-1600℉ for prolonged periods of time. 

Application

1.Construction field: It is commonly used in structural supports, handrails, railings, etc. of buildings. Because of its beautiful, durable and corrosion-resistant properties, it can maintain a good appearance and performance in various climatic conditions. For example, many modern high-rise buildings will use stainless steel pipes for external decoration and internal piping systems.

2.Medical field: commonly used in the manufacture of medical apparatus and equipment, such as surgical instruments, infusion tubes, etc., because it is easy to clean and disinfect, and will not have adverse effects on the human body. Automobile manufacturing: can be used in the exhaust system of automobiles, fuel delivery pipelines and other components.

3.Chemical field: Due to its excellent chemical corrosion resistance, it is widely used in pipeline conveying systems in chemical plants for conveying various corrosive chemicals and liquids.

4.Food and beverage industry: It meets hygiene standards and can be used in food processing equipment, beverage conveying pipes, etc. For example, stainless steel pipes are common in breweries, dairy plants, and other places. Oil and gas industry: able to withstand high pressure and harsh environmental conditions, suitable for the extraction, transportation and storage of oil and gas.

In short, stainless steel pipes play an important role in many industrial and civil fields because of their excellent performance.

Chemical properties

1. Corrosion resistance: Stainless steel pipe has excellent corrosion resistance and can resist the erosion of most acid, alkali and salt solutions. This is due to the formation of a thin and dense chromium oxide protective film on its surface, which prevents the internal metal from being further oxidized.

For example, in an environment containing chloride ions, such as seawater, stainless steel pipe can still maintain good stability. 

2. Oxidation resistance: In a high temperature environment, stainless steel pipe is not easy to be oxidized and can maintain its performance and structural integrity.

Like in high temperature pipes in industrial furnaces, stainless steel pipe can be used for a long time without obvious oxidation phenomenon.

Physical characteristics

1. High strength: It has high tensile strength and yield strength, and can withstand large loads and pressures. For example, in building structures, stainless steel pipes can be used as support components.

2. Good toughness: It is not easy to break when it is impacted or deformed by external forces, and has good toughness and ductility. The stainless steel pipes in the automobile exhaust system can adapt to the vibration and deformation of the vehicle during driving.

3. Thermal and electrical conductivity: It has certain thermal and electrical conductivity, but compared with metals such as copper, the thermal and electrical conductivity are slightly worse. However, in some occasions where the requirements for thermal and electrical conductivity are not particularly high, its performance can still meet the demand.

4. Density: The relative density is higher than that of ordinary carbon steel. 

5. Surface gloss: After treatment, the surface of the stainless steel tube is smooth and has a good appearance.
