The Secret of 304 Stainless Steel

1. What is 304 stainless steel?

304 stainless steel is a common material in stainless steel, also known as 18/8 stainless steel in the industry. Its density is 7.93 g/cm ³， Also known as 18/8 stainless steel in the industry. High temperature resistance of 800 ℃, with good processing performance and high toughness, widely used in industrial and furniture decoration industries, as well as food and medical industries.

2. Characteristics of 304 stainless steel

Corrosion resistance: 304 stainless steel has excellent corrosion resistance and can resist the corrosion of most corrosive media such as acids, alkalis, and salts. Therefore, it is widely used in industries such as chemical, pharmaceutical, and food processing.
Heat resistance: 304 stainless steel has good heat resistance, which can maintain its mechanical and corrosion resistance at high temperatures. Therefore, it is widely used in the manufacturing of boilers, heat exchangers and other equipment.
Low temperature strength: 304 stainless steel can still maintain high strength at low temperatures, so it is widely used in the manufacturing of refrigeration equipment, low-temperature containers, etc.
Mechanical properties: 304 stainless steel has good mechanical properties, such as yield strength, tensile strength, elongation, etc., and is therefore widely used in the manufacturing of mechanical parts, building structures, etc.
Easy to process: 304 stainless steel has good plasticity and machinability, and can be processed and manufactured through cold processing, hot processing, welding, and other methods.

3. How to distinguish the authenticity of 304 stainless steel?

Use stainless steel identification solution: Drop the identification solution onto stainless steel. If it turns red within a few minutes, it indicates that it is not 304 stainless steel; If there is no discoloration, it indicates 304 stainless steel.
Look at the label: 304 stainless steel produced by legitimate manufacturers usually has labels such as “304” or “SUS304” on the packaging or products.
Look at the price: The price of 304 stainless steel is relatively high. If the price is too low, it is likely to be a counterfeit product.
Magnetic testing: 304 stainless steel is usually non-magnetic. If it has strong magnetism, it is likely to be a counterfeit or inferior product.

4. How to maintain 304 stainless steel?

Cleaning: Use a mild cleaning agent and soft cloth for cleaning, avoid using hard objects such as steel balls to scratch the surface, and avoid scratching the surface.
Avoid contact with corrosive substances: Avoid contact with corrosive substances such as acids, alkalis, and salts on 304 stainless steel to avoid damaging the surface.
Regular maintenance: Regularly maintain 304 stainless steel, such as coating with rust proof oil, polishing, etc., to extend its service life.

5. Type of 304 stainless steel product

Plate: 304 stainless steel plate is a commonly used stainless steel material with good plasticity and processability. The plate can be used as a raw material to further process into other forms of products.

6. 304 stainless steel pipe

304 stainless steel pipe is one of the most widely used products of 304 stainless steel. It is a hollow, elongated circular steel material widely used in industrial conveying pipelines and mechanical structural components such as petroleum, chemical, medical, food, light industry, mechanical instruments, etc. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in the manufacturing of mechanical parts and engineering structures. Also commonly used as furniture and kitchenware.

304 stainless steel seamless pipe is a long strip steel with a hollow cross-section and no seams around it. Seamless steel pipes have a hollow cross-section and are widely used as pipelines for transporting fluids, such as oil, natural gas, gas, water, and certain solid materials. Compared with solid steel such as round steel, steel pipes are lighter in weight when their bending and torsional strength is the same. They are an economical section steel and are widely used in the manufacturing of structural and mechanical parts, such as petroleum drill rods, automotive transmission shafts, bicycle frames, and steel scaffolding used in construction. Using steel pipes to manufacture circular parts can improve material utilization, simplify manufacturing processes, save materials and processing time, such as rolling bearing rings, jack sleeves, etc. Steel pipes have been widely used for manufacturing. Steel pipes are still an indispensable material for various conventional weapons, and gun barrels and barrels need to be made of steel pipes. Steel pipes can be divided into round pipes and irregular pipes according to their cross-sectional area and shape. Due to the fact that under the condition of equal perimeter, the circular area is the largest, and circular pipes can transport more fluid. In addition, when the circular section is subjected to internal or external radial pressure, the force is relatively uniform, so the vast majority of steel pipes are circular. However, circular pipes also have certain limitations. For example, under the condition of planar bending, circular pipes are not as strong as square and rectangular pipes in terms of bending strength. Some agricultural machinery skeletons, steel and wood furniture, etc., commonly use square and rectangular pipes. Special shaped steel pipes with other cross-sectional shapes are required for different purposes.

304 stainless steel welded steel pipe refers to a steel pipe with surface seams that is formed by bending and deforming steel strips or plates into circular, square, or other shapes and then welding them. The billet used for welding steel pipes is steel plate or strip. According to different welding methods, it can be divided into arc welded pipes, high-frequency or low-frequency resistance welded pipes, gas welded pipes, furnace welded pipes, Bondi pipes, etc. Welded steel pipe: used in petroleum drilling and mechanical manufacturing industries, etc. Furnace welded pipes: can be used as water and gas pipes, and large-diameter straight seam welded pipes are used for high-pressure oil and gas transportation, etc; Spiral welded pipes are used for oil and gas transportation, pipe piles, bridge piers, etc. According to the shape of the weld seam, it can be divided into straight seam welded pipes and spiral welded pipes.

The application scenarios of 304 stainless steel seamless pipes and welded steel pipes are slightly different. Seamless steel pipes are mainly used for conveying fluids, manufacturing mechanical parts, and other fields, while welded steel pipes are widely used in industries such as oil drilling and production, mechanical manufacturing, and construction.
