How to deal with stainless steel angle bar rust
Stainless steel angle bar has the ability to resist atmospheric oxidation, that is, non-rust, and it also has the ability to resist corrosion in media containing acid, alkali, and salt, that is, corrosion resistance. However, the size of its anti-corrosion ability varies with the chemical composition of the steel itself, the mutual state, the use conditions and the type of environmental media. Such as 304 material, in a dry and clean atmosphere, it has absolutely excellent corrosion resistance, but it is moved to the seaside area, in the sea fog containing a lot of salt, it will quickly rust. Therefore, it is not any kind of stainless steel angle bar, which is corrosion-resistant and does not rust at all times.
Therefore, in order to ensure that the metal surface is permanently bright and not rusted, we recommend:
1. The surface of the decorative stainless steel angle steel must be cleaned and scrubbed frequently to remove attachments and eliminate external factors that cause rust.
2. There is a kind of 201 and 202 stainless steel angle steel on the market that is easy to rust in coastal areas and is suitable for use in an environment without industrial pollution and air corrosion.
3. 304 stainless steel angle steel should be used in coastal areas, 304 material can resist seawater corrosion
