1.Stainless steel is exposed to humid environments. In the presence of water and oxygen, organic acids are formed, which then corrode and damage the surface of stainless steel.

2.Stainless steel products can suffer mechanical damage to their surface protective film during installation due to the mechanical damage caused by installation tools. For example, when installing stainless steel bolts in outdoor curtain wall projects, the wrench may cause mechanical damage to the bolt head at the point of contact. After being washed by rainwater, slight surface rust may appear on the stainless steel bolt head.

3.Dust, impurities, or metal particles on the surface of stainless steel can easily react with the stainless steel in humid air, accelerating its corrosion.

4.Stainless steel surfaces are susceptible to chemical corrosion when exposed to acids, alkalis, and salts. For example, 316 stainless steel products (which are more corrosion-resistant than 304 stainless steel) are generally chosen for curtain wall fasteners in coastal cities because the high salt content in the air in coastal cities easily corrodes stainless steel.

  Therefore, to keep stainless steel products shiny and prevent corrosion, it is essential to choose the correct material. The stainless steel fasteners produced by Xiuxin meet the standard requirements of 304 stainless steel, and the 304 material can withstand a salt spray test of more than 48 hours in the laboratory. At the same time, stainless steel products should be cleaned and maintained during use to remove surface impurities to prevent reactions and corrosion.
