Performance Comparison of Stainless Steel for Electroplating Chuck
Edit:Dongguan City Xin Sen Electronics Co., Ltd   PublicDate:2017-10-26


Electroplating chuck raw material stainless steel Performance comparison:


 316 and 316L stainless steel are molybdenum-containing stainless steel.  316L stainless steel is slightly higher than the 316 stainless steel. Stainless steel has a wide range of uses.  316 stainless steel also has a good performance of chloride erosion, so it is usually used in marine environments.  316L 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.
 Corrosion resistance
 316 stainless steel corrosion resistance is better than 304 stainless steel, in the pulp and paper production process has a good corrosion resistance.  And 316 stainless steel is also resistant to erosion of marine and erosive industrial atmospheres.
 In general, 304 stainless steel and 316 stainless steel in the chemical corrosion resistance is not very different, but in some specific medium to distinguish.
 The initial development of stainless steel is 304, in some cases, this material is more sensitive to point corrosion (PittingCorrosion).  An additional 2-3% increase in molybdenum can reduce this sensitivity, so that the birth of the 316.  In addition, these additional molybdenum can also reduce the corrosion of certain hot organic acids.


 316 stainless steel almost become the food and beverage industry standard materials.  Due to the shortage of molybdenum elements in the world and 316 stainless steel in the nickel content more 316 stainless steel price is more expensive than 304 stainless steel
 Point corrosion is a phenomenon mainly caused by the deposition of stainless steel surface corrosion, which is due to lack of oxygen and can not form a protective layer of chromium oxide.
 Especially in small valves, the possibility of deposition on the valve plate is very small, so the point of corrosion is also rare.
 In all types of water medium (distilled water, drinking water, river water, boiler water, sea water, etc.), 304 stainless steel and 316 stainless steel corrosion resistance is almost the same, unless the medium chloride content is very high, then 316 stainless steel more suitable.
 In most cases, 304 stainless steel and 316 stainless steel corrosion resistance is not much difference, but in some cases may also be very different, the production of chrome chuck to be specific to the specific analysis.  In general, the valve users should be aware of, because they will be based on the media to select the container and pipe material, do not recommend to the user recommended materials.
 Heat resistance
 In the continuous use of 1600 degrees below the continuous use and below 1700 degrees, 316 stainless steel has good resistance to oxidation.  In the range of 800-1575 degrees, it is best not to continuously use 316 stainless steel, but in the temperature range outside the continuous use of 316 stainless steel, the stainless steel has good heat resistance.  316L stainless steel resistance to carbide precipitation better than 316 stainless steel, available above the temperature range.
 Heat treatment
 Annealing at a temperature in the range of 1850 to 2050 degrees, then rapidly annealing, and then rapidly cooling.  316 stainless steel can not be superheated to harden.
 Welding
 316 stainless steel has good welding performance.  All standard welding methods can be used for welding.  Welding can be used according to the use of 316Cb, 316L or 309Cb stainless steel packing rod or welding electrodes for welding.  The best corrosion resistance of the plating chuck , 316 stainless steel welding section need to be post-weld annealing.  If 316L stainless steel is used, no post-weld annealing is required.
