Rusting problem with screws and nuts
Thread Content
Carbon steel screws and nuts rust very easily, especially in the chemical industry located by the sea. The cost of stainless steel is relatively high, and rusting as well as the difficulty of removing carbon steel screws pose significant problems. Could everyone please explain how their respective companies handle this issue? ； In our daily life, when we notice rust, we simply apply paint to fix it; but when it comes to disassembly, things get much more complicated – some use steel saws, others use gas cutting, and it’s a lot of work.
Brush a layer of lacquer on the screws and nuts, and tighten them when it is half-dry.
Hello, owner – here are all my anti-corrosion methods specifically for bolts. There are currently mature cases in various coastal chemical and power enterprises. Our double-layer coating provides corrosion protection that lasts for over 15 years at a time. Coatings cannot provide effective corrosion protection for the edges of nuts, bolts, and similar components, mainly because the coating on the edges of nuts is thin, making those areas prone to corrosion; once corrosion starts in one spot, it can spread outward. We can explore it in more depth if there’s a chance.
The most common method is painting; rust remover is sprayed during disassembly, and it’s generally not difficult to remove.
Applying molybdenum disulfide can prevent bolts from rusting
