    What are The Factors That Cause Door Control Hardware To Rust?3H HARDWARE analysis: When rust spots are found on the surface of door control hardware accessories, everyone will think that there is a problem with the product quality, how can stainless steel rust? In fact, this view is unilateral, stainless steel has strong corrosion resistance , It is based on the oxide film formed on its surface to prevent the continuous penetration of oxygen atoms and continuous oxidation, thereby obtaining the ability to resist corrosion. When these stable factors are destroyed, rust and corrosion will be occured.

    So what is the main reasons for door control hardware to rust?

    1. Air in coastal areas

    Salty air in coastal areas. The salt in the air will precipitate on the surface of the material. The main components of the salt are NaCl and Cl - they are very aggressive and will aggravate the corrosion and rust of stainless steel.

    2. Exhaust gas from industrial areas and urban areas with intensive transportation technology

    Exhaust gas in industrial areas or traffic-intensive areas will also discolor or corrode stainless steel. The exhaust gas contains a large amount of sulfide, carbon oxide and other gases. Once in contact with condensed water, it will cause chemical corrosion of stainless steel.

    3. Strong detergents and sewage

    Strong cleaning agents (such as acid or iron-containing chemical experiments) will have some negative effects with stainless steel enterprises. The same is true for water that has been "polluted" by molten rust, such as water containing iron salts, or rust water that has dissolved rust itself. When water splashes on stainless steel, it may also develop and cause rust.

    The above are the main reasons 3H HARDWARE thinks that  why door control hardware to be rust.If you have the different idea or want to know more about door control hardware accessories,please tell us.
