Anti-Corrosion Method for Steel

Anti-Corrosion Method for Steel

Steel is a material with a certain shape, size and performance made from steel ingots, billets or steel through pressure processing. Most of the steel processing is through pressure processing, so that the processed steel produces plastic deformation. In today's increasingly poor air quality, steel exposed to the outdoors for an extended time is prone to corrosion. In this blog post, we will introduce several steel corrosion protection methods.


Generally, when manufacturing steel, manufacturers will consider adding corrosion coating for steel. If the coating is dense, it can prevent the penetration of gases and corrosive liquids, and can well prevent the accumulation of static electricity in the coating. Its high conductivity can prevent the physical and chemical reactions of acid-base corrosive media. In addition, the coating has high hardness, impact resistance, smoothness and plumpness. Its temperature resistance range is -45℃-150℃. It has a high thermal shock coefficient and good adhesion. Therefore, it is suitable for coating in various acid-base gases and liquids, solvents, intermediates and partial concentrations of salts to resist corrosion and protect organisms from corrosion for a long time.


The bottom layer of the coating is a galvanized layer, and the surface layer is a stainless-steel layer, forming a stepped coating, which is applied to hydraulic steel structures. After a lot of research and testing, economical and satisfactory anti-corrosion effects of steel structures have been achieved. The principle is to use some form of heat source to heat the metal spraying material to form molten particles. Under the action of power, it will impact and sink to the surface of the substrate at a certain speed to form a metal coating with certain characteristics. The coating has strong anti-corrosion and acid-base resistance, so it can meet the anti-corrosion requirements of different occasions. The steel structure, wall surface and industrial equipment surface of the acid-base workshop can be coated with paint in addition to the anti-corrosion on the ground of the main workshop to achieve good anti-corrosion effect.


Another effective anti-corrosion method is metal thermal spraying. It uses a certain form of heat source to heat the steel spray material to form molten particles. Under the high impact, it impacts and sinks to the surface of the substrate at a certain speed to form a metal coating with certain characteristics. It uses thermal spraying technology to treat the surface of base materials such as hydraulic steel structural parts to obtain a corrosion-resistant and wear-resistant metal protective coating, thereby improving the corrosion resistance and wear resistance of hydraulic steel structural parts.


In conclusion, these are some of the most popular and effective major anti-corrosion methods for steel. If you find this information useful, share our article on social media and don't forget to follow CUMIC Steel on LinkedIn and Facebook for more future updates!
