904L stainless steel square tube

The use of 904L stainless steel square pipe with the development of the economy has become more extensive, people are closely related to stainless steel square pipe in daily life, but many people do not know much about the performance of stainless steel square pipe, and they know less about the maintenance of stainless steel square pipe. Many people think that stainless steel square pipe is never rusty, in fact, stainless steel square pipe corrosion resistance is good. The reason is that the surface forms a passivation film, which in nature exists in the form of a more stable oxide. That is to say, although the stainless steel square pipe is different according to the use conditions, the degree of oxidation is not the same, but it is eventually oxidized, which is usually called corrosion.

904L stainless steel square tube surface of the trademark, film, with warm water, weak detergent to wash, binder composition, use alcohol or organic solvents (**, benzene) scrub.

904L stainless steel square pipe surface grease, oil, lubricating oil pollution, clean with a soft cloth, then clean with neutral detergent or ammonia solution or with special detergent. Seamless stainless steel square pipe surface with bleach and various acids attached, immediately wash with water, and then soak with ammonia solution or neutral carbonated soda water solution, wash with neutral detergent or warm water. The surface of the stainless steel square tube has a rainbow pattern, which is caused by excessive use of detergent or oil, and can be washed with warm water neutral detergent when washing.

Rust caused by dirt on the surface of 904L stainless steel square pipe can be washed with 10% nitric acid or abrasive detergent, or special detergent can be washed. As long as we use the correct maintenance method, we can extend the service life of the stainless steel square pipe and maintain its clean, bright and gorgeous appearance.

All the metal surfaces exposed in the corrosive environment undergo electrochemical or chemical reactions and are uniformly corroded. The parts of the passivation film on the surface of the seamless stainless steel square tube with weak corrosion resistance form pitting reaction due to self-excited reaction, forming small holes, coupled with the proximity of chloride ions, forming a strong corrosive solution and accelerating the speed of corrosion reaction. There are also intergranular corrosion cracking inside the stainless steel square tube, all of which destroy the passivation film on the surface of the stainless steel square tube. Therefore, the surface of the stainless steel square pipe must be regularly cleaned and maintained to maintain its gorgeous surface and extend its service life. When cleaning the surface of the stainless steel square pipe, attention must be paid to the occurrence of no surface scratches, avoid the use of bleaching ingredients and abrasive detergent, steel balls, grinding tools, etc., in order to remove the washing liquid, wash the surface with clean water at the end of the washing. Stainless steel square pipe surface dust and easy to remove dirt, can be washed with soap, weak detergent or warm water.
