In many people’s perception, stainless steel custom statue will not rust. But in some cases, stainless steel also get rusty. In fact, there are many other uncontrollable factors that corrode the surface of stainless steel sculptures. The rust resistance and corrosion resistance of stainless steel are due to the formation of a chromium-rich oxide film on its surface. Therefore, when the surface of the stainless steel public sculptures adheres to containing acids, alkalis, and salts, it will easily cause local corrosion.
Stainless steel city sculpture is made of cold-rolled plates. Different model plates have different levels of corrosion resistance in the environment. Different features and attributes of stainless steel materials result in different corrosion. There are many types of stainless steel models, including 200 series, 300 series, 400 series. Under different high humidity and salt content environment, the selected stainless steel material varies, so rust may appear.
The composition of 304 is 18Cr-9Ni, which is the most widely used stainless steel and heat-resistant steel, which also can be used in food production equipment. The performance of 304 stainless steel is enough to resist the surrounding natural environment in the general indoor and outdoor environment. In contrast, the corrosion resistance and other attributes of of 201 is poor, so the price is cheaper. For long-term use, it is generally recommended to use 304 for sculptures cast, the most cost-effective model plates.
In addition to the stainless steel model that will affect the performance of the large sculptures, the welding process is also a very important process making stainless steel sculptures. If the welding is not well done, which will easily lead to corrosion of city sculptures. Therefore, you should choose experienced manufacturing company. Besides, the daily post-maintenance of sculptures are also important. It is better to maintain the works according to experts’ methods.
