022Cr17Ni12Mo2 is stainless steel material.
022Cr17Ni12Mo2 stainless steel, also known as titanium steel, 316L stainless steel-,Add Mo (2~3%) ,Excellent pitting resistance, high temperature? Creep? Strength excellent...
022Cr17Ni12Mo2 is a molybdenum-containing stainless steel species, due to the molybdenum content of the steel, the total performance of the steel is superior to the 310 and 304 stainless steel, high temperature conditions, when the concentration of sulfuric acid is less than 15% and higher than 85%, 316L stainless steel has a wide range of uses.022Cr17Ni12Mo2 stainless steel also has a good resistance to chloride corrosion. So it is usually used in marine environment.
022Cr17Ni12Mo2 stainless steel maximum carbon content of 0.03, can be used after welding can not be annealed and the need for maximum corrosion resistance in the use.

022Cr17Ni12Mo2 is a molybdenum stainless steel species, due to the molybdenum content of the steel, the total performance of the steel is better than 310 and 304 stainless steel, high temperature conditions, when the concentration of sulfuric acid is less than 15% and higher than 85%, 316L stainless steel has a wide range of uses.022Cr17Ni12Mo2 stainless steel also has a good resistance to chloride attack, so usually used in marine environments. So it is usually used in marine environment.
022Cr17Ni12Mo2 stainless steel has a maximum carbon content of 0.03, which can be used in applications that cannot be annealed after welding and require maximum corrosion resistance
Corrosion resistance
Corrosion resistance is superior to that of 304 stainless steel, and it has good resistance to corrosion in the production process of pulp and paper. And 022Cr17Ni12Mo2 stainless steel is also resistant to marine and aggressive industrial atmospheres.
Heat resistance
In intermittent use below 1600 degrees and in continuous use below 1700 degrees, 022Cr17Ni12Mo2 stainless steel has good oxidation resistance. In the range of 800-1575 degrees, it is best not to continuous role 022Cr17Ni12Mo2 stainless steel, but in the continuous use of 022Cr17Ni12Mo2 stainless steel outside the temperature range, the stainless steel has good heat resistance. 022Cr17Ni12Mo2 stainless steel resistance to carbide precipitation performance is better than 06Cr17Ni2Mo2 stainless steel
Heat treatment
Annealed in the temperature range of 1850-2050 degrees, then annealed rapidly, and then cooled rapidly. 316L stainless steel can not be hardened by heat treatment.
Welding
022Cr17Ni12Mo2 stainless steel has good welding performance. All standard welding methods can be used for welding. Welding can be done with 316Cb, 316L or 309Cb stainless steel filler rod or electrode, respectively, depending on the application. For optimum corrosion resistance, the welded section of 06Cr17Ni2Mo2 stainless steel steel needs to be annealed after welding. If 022Cr17Ni12Mo2 stainless steel is used, no post-weld annealing treatment is required.
Typical uses
Heat exchangers for equipment used in pulp and paper, dyeing equipment, film rinsing equipment, piping, and materials for the exterior of buildings in coastal areas.
