What does the L in 304L stainless steel pipe mean? 2018-03-28 Recently, a customer asked what does the L in 304L stainless steel pipe mean? Today, the stainless steel editor will give you a popular science: L stands for low-carbon low. As a low-C 304 steel, its corrosion resistance is similar to that of 304 under normal conditions, but after welding or stress relief, its resistance to intergranular corrosion is excellent; it can also maintain good resistance without heat treatment Corrosion resistance, use temperature -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. 304L means low-carbon 304 stainless steel, with a carbon content of 0.03%, Ni: 9-13, and its strength is slightly worse than that of 304. The corrosion resistance is stronger, and the corrosion resistance is better than 304.
