Properties and uses of 316 and 316L stainless steel

Date:2023-06-19View:243Tags:Drill Pipe,Piling Pipe,Stainless Steel Bar

316 and 317 stainless steel are molybdenum-containing stainless steel species, and the molybdenum content in 317 stainless steel is slightly higher than that of 316 stainless steel. Due to the molybdenum in the steel, the overall performance of this steel is better than that of 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 also has good chloride attack properties, so it is often used in marine environments.

316/316L stainless steel pipe

316L stainless steel has a maximum carbon content of 0.03 and can be used in applications where annealing after welding is not possible and where maximum corrosion resistance is required.
Corrosion resistance
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 resistant to marine and aggressive industrial atmospheres.
Heat resistance
For intermittent use below 1600 degrees and continuous use below 1700 degrees, 316 stainless steel has good oxidation resistance. In the range of 800-1575 degrees, it is best not to use 316 stainless steel continuously, but when 316 stainless steel is used continuously outside this temperature range, the stainless steel has good heat resistance. The carbide precipitation resistance of 316L stainless steel is better than that of 316 stainless steel, and the above temperature range can be used.
heat treatment
Annealed in the temperature range of 1850-2050 degrees, then rapidly annealed, then rapidly cooled. 316 stainless steel cannot be hardened by heat treatment.
welding
316 stainless steel has good welding properties. All standard welding methods can be used for welding. 316Cb, 316L or 309Cb stainless steel filler rods or welding rods can be used for welding according to the application. For optimum corrosion resistance, welded sections of 316 stainless steel require post-weld annealing. If 316L stainless steel is used, post weld annealing is not required.
Typical use
Pulp and paper equipment heat exchangers, dyeing equipment, film processing equipment, pipes, exterior materials for buildings in coastal areas.
