What are The Application Advantages of 316L Stainless Steel Pipe?

Oct. 12, 2020


What are the advantages of 316L Stainless Steel Pipe? What are the main applications?


The carbon content of 316L stainless steel pipe is 0.03, which can be used in applications where annealing cannot be carried out after welding and corrosion resistance is required. 316 and 317 stainless steels are stainless steels containing molybdenum.


The content of molybdenum in 317 stainless steel is slightly higher than that of 316 stainless steel. Due to the molybdenum in steel, the overall performance of this steel is better than 310 and 304 stainless steel. Under high temperature conditions, when the concentration of sulfuric acid is lower than 15% and higher than 85%, 316 Stainless steel has a wide range of uses. 316 stainless steel pipe also has good resistance to chloride corrosion, so it is usually used in marine environments.


Corrosion resistance of 316 stainless steel pipe


The corrosion resistance is better than 304 Stainless Steel, and it has good corrosion resistance in the production process of pulp and paper. And 316 stainless steel is also resistant to the erosion of the ocean and corrosive industrial atmosphere. 316 stainless steel has good oxidation resistance in intermittent use below 1600 degrees and continuous use below 1700 degrees.


In the range of 800-1575 degrees, do not continuously act on 316 stainless steel, but when 316 stainless steel is continuously used outside this temperature range, the stainless steel has good heat resistance. 316L stainless steel pipe has better resistance to carbide precipitation than 316 stainless steel, and the above temperature range can be used.

Annealing in the temperature range of 1850-2050 degrees, then rapid annealing, and then rapid cooling.


316 stainless steel cannot be hardened by heat treatment


316 Stainless Steel has good welding performance. All standard welding methods can be used for welding. During welding, 316Cb, 316L or 309Cb stainless steel filler rods or welding rods can be used according to the application. In order to obtain good corrosion resistance, the welded section of 316 stainless steel needs to be annealed after welding. If 316L stainless steel is used, post-weld annealing treatment is not required.


Typical uses: Pulp and paper-making equipment, heat exchangers, dyeing equipment, film washing equipment, pipelines, and exterior materials for buildings in coastal areas.
