316 And 316L Stainless Steel Tips

316 and 316L stainless steel 316 and 317 stainless steel (see below for the performance of 317 stainless steel) are molybdenum-containing stainless steel.

The molybdenum content in 317 stainless steel is slightly higher than that in 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 resistance to chloride attack, so it is often used in marine environments. 316L stainless steel has a maximum carbon content of 0.03 and can be used in applications where annealing cannot be performed after welding and where maximum corrosion resistance is required. Corrosion resistance: The corrosion resistance is better than that of 304 stainless steel, and it has good corrosion resistance in the pulp and paper production process. Moreover, 316 stainless steel is also resistant to corrosion from the ocean and corrosive industrial atmosphere. Heat resistance: 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, it is best not to continuously use 316 stainless steel, but when 316 stainless steel is used continuously outside this temperature range, the stainless steel has good heat resistance. The resistance to carbide precipitation of 316L stainless steel is better than that of 316 stainless steel, and it can be used in the above temperature range. Heat treatment: Annealing in the temperature range of 1850-2050 degrees, followed by rapid annealing and then rapid cooling. 316 stainless steel cannot be hardened by heat treatment. Welding 316 stainless steel has good welding properties. Welding can be carried out using all standard welding methods. When welding, 316Cb, 316L, or 309Cb stainless steel filler rods or welding rods can be used for welding according to the purpose. To obtain the best corrosion resistance, the welded section of 316 stainless steel needs to be annealed after welding. If 316L stainless steel is used, post-weld annealing is not required. Typical uses: Heat exchangers for pulp and paper equipment, dyeing equipment, film processing equipment, pipes, and exterior materials for buildings in coastal areas.
