316L Stainless Steel Pipe Description
316L stainless steel pipe contains a lower carbon content compared to 316 stainless steel pipe, making it suitable for welding applications. The reduced carbon content significantly minimizes the precipitation of carbides in the heat-affected zone near the weld, which is closely linked to intergranular corrosion of stainless steel in certain environments. Notably, there is no need to anneal weld joints prior to using the completed metal form. 316L stainless steel pipe is the second most prevalent stainless steel after 304, offering superior corrosion resistance compared to 304. It also exhibits improved high-temperature resistance, up to 1000 degrees. Widely regarded as a universal stainless steel material, 316L stainless steel pipe is extensively used in the chemical industry due to its exceptional corrosion resistance.
