Q: Why choose us?

A: EST Chemical Group has been focusing on the industry for more than 10 years. Our company is leading the world in the fields of metal passivation, rust remover and electrolytic polishing liquid with a large research & development center. We provide environmentally friendly products with simple operation procedures and guaranteed after-sale service to the world.

Q: What is the main components of the passivation film? How thick of passivation membrane change the material composition?Affect the use of the product properties (electrical conductivity, mechanical properties, etc.)?

A: Strictly speaking,Passivation membrane is not form a new material,the main ingredients is original composition of stainless steel,through the micro chemical reaction of passivation,We only changed the metal chemical lively property of material surface.Turned the chemical active metal surfaces into chemical inert metal surface (is chromium oxide and nickel oxide combination together)

Q:Why the stainless steel products need passivation?

A:With the development of economy, more and more products are exported to Europe and the United States,But because of need to travel through the sea, abominable(terrible/awful) environment is easy to cause the products rust,In order to ensure the product does not rust on the sea, so must need to do a passivation treatment, in order to enhance product antirust corrosion resistance

Q: The products when to need adopt pickling passivation craft?

A: Products in the process of welding and heat treatment(In order to increase the products hardness , such as the heat treatment process of martensitic stainless steel).Because of the product surface will form black or yellow oxides on the high temperature condition, This oxides will affect the appearance of the product quality, so must remove the surface oxides.
