Surface treatment of stainless steel pipe fittings cross

　　After the processing and forming of stainless steel pipe fittings cross, the surface must be treated to make the performance of stainless steel pipe fittings cross,more excellent. It can be said that if the stainless steel pipe fittings cross,are not treated, its advantages will not be shown. So what kind of treatment should the surface of stainless steel pipe fittings cross,go through?

　　Usually the most common surface treatment methods are as follows: surface natural color whitening treatment, surface specular finish, surface coloring treatment.

　　Surface natural color whitening treatment: in the process of SS316 Stainless Steel Pipe Fittings Cross,processing, black oxide skin is produced after rolling, binding, welding or artificial surface heat treatment. This kind of hard gray black oxide skin is mainly composed of nicr2o4 and NIF, two eo4 components.

　　At present, there are two main methods to stainless steel cross treat oxide skin:

　　Sandblasting (shot) method: the main method is to spray micro glass beads to remove the black oxide skin on the surface.

　　Chemical method: use a kind of pollution-free pickling passivation paste and normal temperature non-toxic cleaning solution with inorganic additives for immersion. So as to achieve the goal of whitening the natural color of stainless steel cross. After treatment, it basically looks like a dull color. This method is suitable for large and complex products.

　　Polishing method of stainless steel cross surface: according to the complexity of stainless steel cross products and different requirements of users, mechanical polishing, chemical polishing, electrochemical polishing and other methods can be used to achieve the specular luster.

　　Surface coloring treatment: Stainless Steel Cross Coloring not only gives various colors to stainless steel products, increases the variety of designs, but also improves the wear resistance and corrosion resistance of products.
