304L Stainless steel Pipe/Tube-Stainless steel Pipe/Tube-Shandong Aofeng Metal Material Co.,Ltd-

304L stainless steel pipe belongs to the international stainless steel marking method. 304L stainless steel pipe-S30403 (American AISI, ASTM) 304L corresponding to the Chinese grade is 00Cr19Ni10, characteristics and uses: steel with lower carbon content than 0Cr19Ni9, superior resistance to intergranular corrosion, for parts without heat treatment after welding.

304L stainless steel pipe 18Cr-8Ni- low carbon is a low-C 304 steel. Under normal conditions, its corrosion resistance is similar to that of 304 steel, 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 use temperature is -196℃~800℃. It is applied to outdoor machines in the chemical, coal, and petroleum industries that require high grain boundary corrosion resistance, heat-resistant parts for building materials and parts with difficult heat treatment.
