A brief introduction to the 304 stainless steel pipe

Release time:


304 stainless steel pipe is a common material in stainless steel, with a density of 7.93g/cm³, which is also called 18/8 stainless steel in industry. Can withstand 800 ℃ high temperature, good processing performance, high toughness. It is widely used in industry and furniture decoration industry as well as food and medical industry.


Common marking methods in the market include06Cr19Ni10 and SUS304, where 06Cr19Ni10 usually means national standard production, 304 usually means ASTM standard production, and SUS 304 means Japanese standard production.

304 stainless steel pipe is a kind of multi-purpose stainless steel, which is widely used in the manufacture of equipment and parts that require good overall performance (corrosion resistance and formability). In order to maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 18% chromium and more than 8% nickel.

304 stainless steel pipe is widely used chromium nickel stainless steel products. As a widely used steel, it has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; it has good hot working properties, such as stamping and bending without heat treatment. 304 stainless steel pipe is resistant to atmospheric corrosion, but if it is an industrial environment or a heavily polluted area, it needs to be cleaned in time to avoid corrosion. Suitable for food processing, storage and transportation. Good processability and weldability.


UseMost of the requirements for 304 stainless steel pipes are to maintain the original appearance of the building for a long time. When determining the type of stainless steel pipe to be selected, the main considerations are the required aesthetic standards, the corrosivity of the local atmosphere and the cleaning system used. However, other applications 304 stainless steel tubing increasingly seek structural integrity or impermeability. For example, roofs and side walls of industrial buildings. In these applications, the owner's construction cost may be more important than aesthetics, and the surface may not be particularly clean. The effect of using 304 stainless steel pipes in a dry indoor environment is very good. However, if you want to maintain your appearance outdoors in the countryside and cities, you need to wash it frequently. In industrial and coastal areas with serious pollution, the surface of 304 stainless steel pipes will be very dirty or even rusty.
