How to clean the surface of stainless steel castings?

Stainless steel castings with recommended clean surfaces fall into two categories:
       Dry, wet and dry cleaning methods are mainly used in the blasting process. The wet hydraulic cleaning methods are mainly solution reduction and water deoxidation. The following are the two methods of cleaning the surface of stainless steel castings, dry and wet, for your reference.
       The dry cleaning method is mainly to clean the surface of the friction stainless steel casting during the blasting process. The blasting process is simply driven by compressed air, so that the projectile is sprayed on the surface of the stainless steel casting at a certain speed, and the surface is clear with sand and iron oxide. However, due to the low efficiency, unevenness and poor cleaning effect of the friction cleaning method, the factories that have been created are almost eliminated.
       The wet principle mainly affects the active class rational method, high voltage pulse generator and discharge through special electrodes placed in the water, a large hydraulic shock. Because the elastic modulus of stainless steel casting surface adhesion and casting and vibration frequency are different, so as to achieve the purpose of deoxidation. There is a relatively effective cleaning efficiency for stainless steel castings with complex shapes, such as deep holes, blind holes, and inner cavities. Is the most widely used series of stainless steel castings, casting surface cleaning.
       Stainless steel can be divided into austenitic stainless steel, martensitic stainless steel and ferritic stainless steel according to the structure.
       Austenitic stainless steel is a kind of stainless steel. The use of austenitic stainless steel is the largest structure. In theory, it is not magnetic, but austenitic stainless steel can generate a magnetic field after cold working. The reason is that in the process of Customized Alloy Steel Precision Investment Construction Machinery Casting Parts XK-A011 processing, when the austenitic stainless steel is heated to a temperature higher than the temperature and kept for a period of time, it will transform into austenitic stainless steel, but the stainless steel casting needs to be cooled and formed. From the tensite to martensite transformation temperature, its structure begins to transform into martensite, and it stops changing until the temperature drops below the transformation temperature to form a martensite structure.
       In the production of stainless steel castings and stable austenitic stainless steel, processing deformation and processing methods may affect the transformation of martensitic stainless steel. The above are two common cleaning methods for the surface of stainless steel castings. It is necessary to remind customers that these two cleaning methods are not only suitable for Stainless steel castings, most of the post-processing and forming process of metal casting products need to clean the surface, in the process of metal casting products is an essential process, the surface cleaning of castings, the main role is to contact the surface of the metal foundry sand, and a series of The iron oxide and other impurities make the stainless steel casting, the metallic luster of the stainless steel surface reach the product standard, so it is very important to clean the surface of the stainless steel casting, everyone must follow the correct way when cleaning the surface of the stainless steel casting. Guarantee the quality of stainless steel casting products.
