The use of stainless steel casting in Dongguan dewaxing casting has become more and more widespread in the market. The products have won the favor of customers because of their own advantages. In the process of use, stainless steel casting will change due to moisture and oxygen in the air. Such a substance can turn a high-strength metal surface into a low-strength compound, so the product needs to be rust-proofed in time when it is processed.

When stainless steel casting is selected for rust prevention, oil and water are generally used for rust prevention. However, no matter which rust prevention method is used in actual use, castings need to clean the dirt on the surface of the product in advance, and To promote the formation of a passivation film on the surface of the product, the temperature of the water required for cleaning is also certain. After cleaning, it needs to be dried with hot compressed air. Then carry out rust prevention.

If Guangdong alloy steel casting rusts, it is difficult to clean the rusted surface. Therefore, the pre-treatment of the product must be done. First, we need to use clean water to soak and clean the product. The main function of soaking is to fill the gaps on the surface of the product to facilitate the later chemical treatment, and then perform chemical degreasing.

When the surface of stainless steel casting needs to remove the oxide scale, mechanical methods can be used, such as grinding, polishing and rolling. Some products need to be cleaned during these treatments. If blackening is directly found, Effective processing in time. After the product is degreasing, there will be more voids on the surface of the product, and it is difficult to remove. If the treatment is not good, it will affect the entire anti-rust treatment.

Guangdong carbon steel casting needs to do a good job of preventing rust both during production and in future use. If such work is not done in place, it will greatly affect the performance and life of the product. The method of deoxidizing the surface of the product is very important and will have a greater impact on the entire rust prevention.
