Stainless steel surface cleaning and derusting method

You can shovel it off with various tools to remove the rust. It can also be dissolved in an acidic solution. After removing the rust, the surface of the iron must be disposed of, coated with a layer of lead, and then painted with paint; Or plated with other metal that is not easy to rust. A more thorough method is to add some other metals to iron to make a stainless alloy. Familiar stainless steel is an alloy made by adding a little nickel and chromium to steel.

It is better to use the information of high carbon steel. Martensitic stainless steel in stainless steel, if you want to make steel plate. Its carbon content is high. It is good to make steel plates, such as 440 stainless steel. 304 stainless steel is austenitic stainless steel with low carbon content. The steel plate is not hard, durable or sharp. Not as good as the steel plate made of martensitic stainless steel. The carbon content of ordinary carbon steel is also high and low. If low carbon steel is used to make steel plate, it is not necessarily better than 304 stainless steel. Because the same information with low carbon content, at least 304 stainless steel has the advantage of stainless steel.

How to remove the rusty stainless steel

Many of them are stainless steel, so the pots used in the kitchen in life. We are not unfamiliar with the term stainless steel. In fact, the full name of stainless steel is stainless acid resistant steel, and stainless steel is the abbreviation. Although stainless steel has stronger corrosion resistance than ordinary pots, it can not be completely prevented. Stainless steel will not rust at all. Today Xiaobian also helps you solve a problem, that is, how to remove rust when stainless steel is rusted. You should listen carefully. It is very practical.

1: Causes of stainless steel rust removal.

When the corrosion resistance of the passive film on the surface of stainless steel is relatively weak, pitting corrosion is formed due to self-excited reaction, 1 first from the cause of stainless steel rust. Then small holes will be formed, and slowly chloride ions will approach, and finally a highly corrosive liquid will be formed, which will further accelerate the corrosion rate of stainless steel. Another reason is the intergranular corrosion cracking in stainless steel, which destroys the passive film on the surface of stainless steel. Therefore, the appearance of stainless steel must be cleaned and maintained frequently, so as to prolong its service life. However, when cleaning the stainless steel surface, pay attention to: the stainless steel surface shall not be scratched; Do not use detergent containing bleaching ingredients and abrasives. If detergent is used, it must be washed with clean water after completion.

2: Stainless steel derusting method.

When the lubricating oil is polluted, 1 when the stainless steel surface is covered with grease. It can be wiped clean with a soft cloth, and then cleaned with neutral detergent or ammonia solution.

Weak detergent or washing. The trademark and film on the surface of stainless steel should be cleaned with warm water or weak detergent. 3 when there is dust or easy dirt on the surface of stainless steel, soap can be used. The binder components should be washed with alcohol or organic solvent.

It can be cleaned with 10% nitric acid or abrasive detergent, 4 when rust stains appear on the stainless steel toilet surface. It can also be cleaned with special detergent. Therefore, if you want stainless steel to maintain a bright and clean appearance and prolong its service life, the above points must be done!

Xiaobian introduced the causes of stainless steel rust, as mentioned above. The reason is very simple, that is, stainless steel will be oxidized after being exposed in the air for a long time, so it will rust. Only when you know the cause of stainless steel rust can you know the solution. When it comes to methods, Xiaobian introduced four methods, which are relatively simple. Generally, neutral detergent is used to remove the embroidery on stainless steel. Of course, you can choose other small series. That's all. I hope the introduction of small series will bring you assistance. Thank you.

Stainless steel is rusty. What can be used to remove it

Use the angle grinder device polishing brush to remove rust. Can you also use stainless steel rust remover to wipe it after application——

How can the rust spots on stainless steel be disposed of

Iron will combine with oxygen - rust. Iron will rust if it is put for a long time. Iron rusts easily. Rust is a compound. When iron is wet for a long time. In addition to its active chemical properties, it is also closely related to external conditions. Moisture is one of the substances that make iron rust easily.
