Thick-walled stainless steel pipe 316l stainless steel thick-walled pipe knowledge thick-walled stainless steel pipe 316l stainless steel thick-walled pipe is molybdenum-containing stainless steel species, due to the presence of molybdenum in the steel, the total performance of the steel is better than 310 and 304 stainless steel, high temperature conditions, when sulfuric acid At concentrations below 15% and above 85%, 316L stainless steel has a wide range of uses. 316L stainless steel also has good chloride attack properties, so it is often used in the marine environment.

The maximum carbon content of 316l stainless steel thick-walled pipes is 0.03, which can be used in applications where welding cannot be performed after annealing and where maximum corrosion resistance is required. 316l stainless steel thick-walled pipe is superior to 304 stainless steel in corrosion resistance and corrosion resistance during production of pulp and paper Medium has good corrosion resistance. And 316L stainless steel is also resistant to the erosion of the ocean and the aggressive industrial atmosphere.
316l stainless steel thick-walled pipe heat resistance in the intermittent use of less than 1600 degrees and in 1700 degrees continuous use, 316L stainless steel has good oxidation resistance. In the range of 800-1575 degrees, it is better not to continuously apply 316L stainless steel, but when the 316L stainless steel is continuously used 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 the above temperature range can be used.
The heat treatment is annealed at a temperature in the range of 1850-2050C, then rapidly annealed and then rapidly cooled. 316L stainless steel cannot be hardened by heat treatment.
316l stainless steel thick-walled pipe welding 316L stainless steel has good welding performance. All standard welding methods can be used for welding. Welding can be based on the use of 316Cb, 316L or 309Cb stainless steel filler rods or electrodes for welding. In order to obtain the best corrosion resistance, the welded section of 316 stainless steel needs post-weld annealing. If 316L stainless steel is used, post-weld annealing is not required.
316l stainless steel thick-walled tube Typical uses Pulp and papermaking equipment Heat exchangers, dyeing equipment, film processing equipment, pipelines, materials for building exteriors in coastal areas.
