2. Wall thickness: The wall thickness of 304 stainless steel seamless pipe is generally between 0.5mm and 40mm, and common wall thicknesses are 1mm, 2mm, 3mm, etc.
3. Length: The length of 304 stainless steel seamless pipe is generally about 6 meters, and customized lengths are also available. During use, the standardization of length can facilitate processing and installation.
Quality Standards for 304 Stainless Steel Seamless Pipes
1. Chemical composition: The chemical composition of 304 stainless steel seamless pipes must comply with relevant standards, mainly including the content of elements such as C, Si, Mn, P, S, Cr, and Ni.
2. Mechanical properties: The mechanical properties of 304 stainless steel seamless pipes in terms of tension, compression, and bending must comply with relevant standards.
3. Surface quality: The surface of 304 stainless steel seamless pipes should be flat and smooth, without defects such as cracks, bubbles, shrinkage holes, and wrinkles.
Advantages of 304 stainless steel seamless pipes
1. Strong corrosion resistance
Since 304 stainless steel seamless pipe contains about 18% chromium and about 8% nickel, it has strong corrosion resistance. Specifically, it can resist some common erosions such as atmosphere, water, steam and other chemicals. Due to its strong corrosion resistance, 304 stainless steel seamless pipe is widely used in the chemical industry, petroleum industry and food processing industry.
2. High strength
The tensile strength of 304 stainless steel seamless pipe is as high as 520MPa, and the yield strength reaches 205MPa. At the same time, its hardness is also relatively high, which can reach Rockwell B80 and Brinell 187. These properties make 304 stainless steel seamless pipe have good stability and durability in complex environments such as high temperature, high pressure and heavy load. Therefore, it is widely used in high-demand fields such as petrochemical, automobile and aviation.
3. Beautiful and easy to clean
The surface of 304 stainless steel seamless pipe is smooth and burr-free, which is not easy to hide dirt , and the surface is easy to clean. In addition, it has high gloss and translucent properties, and has a beautiful appearance. These characteristics make 304 stainless steel seamless pipe widely used in residential decoration, furniture manufacturing and kitchen equipment.
4. Good processability
304 stainless steel seamless pipe has good plasticity and weldability, and can be machined, sheet metal processed and welded in various ways. At the same time, its chemical properties are stable, and there will be no problems such as thermal cracks during processing. These characteristics make 304 stainless steel seamless pipe widely used in industrial manufacturing and construction.
