Painting method to prevent SS400 from rusting for a long time.
What is SS400? In JIS (Japanese Industrial Standards), there is a standard for rolled steel materials known as general structural rolled steel. General structural rolled steel is represented by the material symbol SS, and since the minimum tensile strength is 400 MPa, it is called "SS400." It is a type of steel that is widely used across various fields, making it abundant and inexpensive to obtain. It is characterized by its ease of machining and welding, as well as its high versatility. On the other hand, it is a relatively soft material among steels, making it difficult to use in areas that require high strength, and it is prone to rust, necessitating anti-rust treatment. Therefore, some form of rust prevention treatment is required. Additionally, the surface of the steel is covered with "mill scale," which is formed when the surface becomes hot during the manufacturing process and combines with oxygen. If the mill scale is not removed, the anti-rust treatment will not last long. There are two methods for removing mill scale: "pickling" and "blasting," with blasting being superior for preventing rust over a longer period. By completely removing all foreign substances like mill scale through blasting and applying anti-rust treatment to the formed surface of the substrate, SS400 can remain rust-free for an extended period.
