304/304L Stainless Steel Tube
304 stainless steel pipe is a common material in stainless steel with a density of 7.93 g/cm³; it is also called 18/8 stainless steel, which means it contains more than 18% chromium and more than 8% nickel; it is resistant to high temperatures of 800°C and has good processing performance , with the characteristics of high toughness, it is widely used in industrial and furniture decoration industries and food and medical industries.
Stainless steel 304 pipe has low hardness and good processing properties. Its density is 7.93g/cm³, indicating that its mass is relatively light. The melting point range is 1398~1454℃ and has good heat resistance. The specific heat capacity is 0.50KJ·kg-1K-1, indicating its strong ability to absorb heat. As the temperature rises, the thermal conductivity gradually increases, which is beneficial to heat transfer. The linear expansion coefficient increases with the increase of temperature. It is necessary to pay attention to the influence of temperature changes on pipe size. The resistivity is 0.73×10-6Ω·m2/m, ensuring the stability of conductive performance. The longitudinal elastic modulus is 193KN/mm2, which has good resistance to deformation.
304L Stainless Steel Pipe 18Cr-8Ni-Low Carbon As a low-C 304 steel, its corrosion resistance is similar to that of 304 steel under normal conditions, but after welding or stress relief, its resistance to intergranular corrosion is excellent; In the case of heat treatment, it can also maintain good corrosion resistance, and the operating temperature is -196℃~800℃. It is used in outdoor machines in the chemical, coal, and petroleum industries that require high resistance to grain boundary corrosion, as well as heat-resistant building material parts and parts that are difficult to heat treat.
