The quality of the waterproof casing will directly affect the service life or performance of the wat

For example, in steel, the composition of the steel will necessarily affect the performance of the steel, but for a steel with a fixed composition, the waterproof casing is deformed and processed, and its performance will change. In summary, the main factors that affect the properties of steel are: composition, deformation and temperature. In fact, it is related to the internal structure of the steel. Through a microscope, steel is composed of many small blocks identical to steel plates and, on closer inspection, these blocks belong to several different categories. We usually call them the same blocks.
 
Austenite and ferrite are generally considered to be the two more common forms of structure in steel, i.e., the two-phase structure. The number of phases a steel contains, the proportion of each phase, and the shape of each phase, all directly affect the properties of the steel. That is, if the phase type, ratio, and shape of the steel change, the properties of the steel will change. If waterproof casing products produced with inferior steel are used, it is conceivable that their performance and service life will be greatly affected. Therefore, when using waterproof casing, good and assured waterproof material shall be used so that it can be completed more smoothly after use.
