The powder is typically made of a mixture of resin and pigment, which melts and bonds to the steel when heated. Powder coating provides excellent corrosion resistance and is available in a wide range of colors and finishes. 4. Paint coatings: Painting steel billets with corrosion-resistant paint is another effective surface treatment. The paint forms a protective barrier that prevents moisture and corrosive agents from reaching the steel. Multiple layers of paint may be applied to improve the durability and longevity of the coating. 5. Passivation: Passivation is a chemical process that removes free iron and other contaminants from the surface of the steel billets. This helps to prevent the formation of corrosion and promotes the formation of a protective oxide layer. Passivation is often used in combination with other surface treatments, such as electroplating or powder coating, to enhance their corrosion resistance. It is worth noting that the choice of surface treatment for improved corrosion resistance in steel billets depends on various factors such as the environment in which the billets will be used, the desired lifespan of the steel, and the cost considerations.
