304L stainless steel pipe is a low-carbon upgraded version of 304, produced by precise carbon control rolling process with compact structure and high dimensional accuracy. It inherits all excellent performance of 304 steel and effectively avoids intergranular corrosion and weld cracking caused by high-temperature welding. It requires no secondary solution treatment after welding, saving construction cost and time. With stable pressure resistance and high toughness, it is specially designed for large welded piping projects, widely used in pressure vessels, chemical pipelines, municipal high-pressure pipes and large steel structure welding engineering.
