316 Stainless Steel Tube Knowledge - Corrosion Resistance - 316 Stainless Steel Tube Heat Treatment - 316 Stainless Steel Tube Welding

The maximum carbon content of 1 316L stainless steel is 0.03, which can be used in applications where annealing cannot be performed after welding and maximum corrosion resistance is required.
2 316 and 317 stainless steels (see below for properties of 317 stainless steel) are molybdenum-containing stainless steels.
The molybdenum content of 3 317 stainless steel is slightly higher than that of 316 stainless steel. Due to the molybdenum content in the steel, the total performance of the 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.
4 316 stainless steel also has good chloride attack properties, so it is often used in the marine environment.
Corrosion resistance of 316 stainless steel pipe 5 Corrosion resistance is superior to 304 stainless steel and has good corrosion resistance in the production of pulp and paper.
6 And 316 stainless steel is also resistant to the erosion of the ocean and the aggressive industrial atmosphere. Heat resistance of 1600 degrees below the intermittent use and in 1700 degrees below continuous use, 316 stainless steel has good oxidation resistance.
7 In the range of 800-1575 degrees, it is better not to continuously apply 316 stainless steel, but when the 316 stainless steel is continuously used outside this temperature range, the stainless steel has good heat resistance.
8 316L stainless steel has better carbide precipitation resistance than 316 stainless steel and can use the above temperature range.
316 stainless steel tube heat treatment 9 Annealed at a temperature in the range of 1850-2050 degrees, followed by rapid annealing, and then rapidly cooled.
10 316 stainless steel cannot be hardened by heat treatment.
316 stainless steel pipe welding 11 316 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.
12 Typical applications Pulp and paper equipment Heat exchangers, dyeing equipment, film processing equipment, pipelines, materials for the exterior of buildings in coastal areas.
