304L stainless steel pipe belongs to the international stainless steel marking method. 304L stainless steel pipe—S30403 (American AISI, ASTM) corresponds to the Chinese grade No. 00Cr19Ni10. Characteristics and applications: steel with lower carbon content than 0Cr19Ni9, with resistance to intergranular corrosion, suitable for parts that do not require heat treatment after welding.
304L Stainless Steel Tube: Element Content: C≤0.03, Ni 8.00～12.00, Cr 18.00～20.00, Mn≤2.0, Si≤1.0, S≤0.030, P≤0.035.
304L Stainless Steel Pipe, 18Cr-8Ni-Low Carbon — As a low carbon version of the 304 steel, it exhibits similar corrosion resistance to 304 steel under normal conditions. However, after welding or stress relief, it boasts enhanced grain boundary corrosion resistance. Without heat treatment, it maintains excellent corrosion resistance, with a service temperature range of -196℃ to 800℃. Suitable for outdoor machinery in the chemical, coal, and petroleum industries where high grain boundary corrosion resistance is required, as well as for heat-resistant components in construction materials and parts that are difficult to heat treat.
