? 00Cr17Ni14Mo2 stainless steel tube, 00Cr17Ni14Mo2 0Cr17Ni12Mo2 for ultra-low carbon steel, the ratio between 00Cr17Ni14Mo2 0Cr17Ni14Mo2 good resistance to intergranular corrosion. Usually used to manufacture chemicals, fertilizers and chemical fiber and other industrial equipment, such as vessels, piping and structural parts. 00Cr17Ni14Mo2 correspondence with the United States 316L. Maximum carbon content of 0.03 1 316L stainless steel tube that can be used can not be annealed after welding and need maximum corrosion resistance applications. Stainless steel tube stainless steel tube 316L stainless steel with the addition of Mo, corrosion resistance, particularly excellent pitting resistance; high-temperature strength is also very good; excellent hardening (after processing weakly magnetic); solid solution non-magnetic. 316L stainless steel grades: 00Cr17Ni14Mo2 chemical composition% C: ≤0.03 Si: ≤1.0 Mn: ≤2.0 Cr: 16.0 ~ 18.0 Ni: 12.0 ~ 15.0 S: ≤0.03 P: ≤0.045 Mo: 2.0 ~ 3.0. 2316 and 317 stainless steel pipe (317 stainless steel performance below) is a stainless steel containing molybdenum species. 3317 stainless steel tube 316 stainless steel is slightly higher than the molybdenum content. Since molybdenum steel, the steel is superior to 310 and the total of 304 stainless steel, high temperature conditions, when the concentration of sulfuric acid is less than 15% and above 85% When, 316 stainless steel having a wide range of uses. 4316 stainless steel pipe also has good resistance to chloride corrosion performance, it is usually used in the marine environment. 5 6 corrosion corrosion resistance than 304 stainless steel tube, with good corrosion performance in the pulp and paper production process. 7 and 316 stainless steel is also resistant to marine and corrosive industrial atmosphere erosion. Intermittent heat resistance in the following 1600 degrees and 1700 degrees in continuous use, the 316 stainless steel has good resistance to oxidation. 8 in the range of 800-1575 degrees, it is best not continuous action 316 stainless steel, but when the temperature outside the range of the continuous use of 316 stainless steel, the stainless steel has good heat resistance. Resistant carbide precipitation performance 9 316L stainless steel better than the 316, the above-mentioned temperature range available. Heat treatment is carried out in 10-degree temperature range 1850-2050 annealed, then rapidly annealed and then rapidly cooled. 11316 stainless steel can not be hardened to heat treatment. 13 12 welding all standard welding methods can be used for welding. Welding with the purpose of, respectively 316Cb, 316L stainless steel or 309Cb welding filler rods or rod. For optimum corrosion resistance, stainless steel welding section 316 require post-weld annealing. If you use 316L stainless steel, it does not require annealing after welding.
