What are the application advantages of 316L stainless steel pipe?

What are the advantages of 316L stainless steel pipe advantages? And what are the main areas of application?

316L stainless steel pipe carbon content of 0.03, can be used after welding can not be annealed and need corrosion resistance in the use of 316 and 317 stainless steel (317 stainless steel performance see later) is a molybdenum stainless steel species. 317 stainless steel content of molybdenum is slightly higher than 316 stainless steel.

The molybdenum content of 317 stainless steel is slightly higher than that of 316 stainless steel. Because of the molybdenum in the steel, the total performance of the steel is better than 310 and 304 stainless steel, high temperature conditions, when the concentration of sulfuric acid is less 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 erosion, so it is usually used in marine environments.

316 stainless steel pipe corrosion resistance

Corrosion resistance is better than 304 stainless steel, has good corrosion resistance in the production process of pulp and paper. And 316 stainless steel is also resistant to marine and aggressive industrial atmospheres. Heat resistance in intermittent use below 1600 degrees and in continuous use below 1700 degrees, 316 stainless steel has good oxidation resistance. In the range of 800-1575 degrees, do not act continuously 316 stainless steel, but in the continuous use of 316 stainless steel outside this temperature range, the stainless steel has good heat resistance.

316L stainless steel pipe resistance to carbide precipitation performance is better than 316 stainless steel, available in the above temperature range.

316 stainless steel pipe heat treatment

Annealed in the temperature range of 1850-2050 degrees, then rapidly annealed, then rapidly cooled.

316 stainless steel can not be hardened by heat treatment

316 stainless steel has good welding performance. It can be welded by all standard welding methods. Welding can be done with 316Cb, 316L or 309Cb stainless steel filler rod or electrode, respectively, 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, no post-weld annealing is required.

Typical applications Heat exchangers for pulp and paper equipment, dyeing equipment, film processing equipment, piping, materials for the exterior of buildings in coastal areas.
