AUSTENITIC GB4237 1Cr12 stainless steel maintenance method

The use of AUSTENITIC GB4237 1Cr12 stainless steel has become more and more extensive with the development of the economy. People are closely related to AUSTENITIC GB4237 1Cr12 stainless steel in daily life, but many people do not know much about the performance of AUSTENITIC GB4237 1Cr12 stainless steel. Maintenance of AUSTENITIC GB4237 1Cr12 stainless steel I know a little more. Many people think that AUSTENITIC GB4237 1Cr12 stainless steel will never rust. In fact, AUSTENITIC GB4237 1Cr12 stainless steel has good corrosion resistance because the surface forms a purified film. In nature, it exists in the form of more stable oxide. That is to say, AUSTENITIC GB4237 1Cr12 stainless steel, although different in oxidation conditions according to different conditions of use, is eventually oxidized, which is usually called corrosion.

All metal surfaces exposed to corrosive environments are electrochemically or chemically reacted, and are uniformly corroded. The corrosion-resistant part of AUSTENITIC GB4237 1Cr12 stainless steel surface-purified film forms pitting corrosion due to self-excitation reaction, resulting in small holes. Together with the aerobic ions approaching, a very corrosive solution is formed, accelerating the rate of corrosion reaction. There is also intergranular corrosion cracking inside AUSTENITIC GB4237 1Cr12 stainless steel, all of which destroys the purified film on the surface of AUSTENITIC GB4237 1Cr12 stainless steel.

Therefore, the surface of AUSTENITIC GB4237 1Cr12 stainless steel must be regularly cleaned and maintained to maintain its surface and extend its service life. When cleaning the surface of AUSTENITIC GB4237 1Cr12 stainless steel, care must be taken not to cause surface scratching, avoid the use of bleaching ingredients and abrasive washing liquid, steel balls. Grinding tools, etc., to remove the washing liquid, rinse the surface with clean water at the end of washing.

1, AUSTENITIC GB4237 1Cr12 stainless steel surface with dust and easy to remove dirt can be washed with a weak soap detergent, adhesive ingredients, using alcohol or organic solvents (ether, benzene) scrub.

2, AUSTENITIC GB4237 1Cr12 stainless steel surface grease, oil lubricant contamination, wipe with a soft cloth, with a neutral detergent or ammonia solution or with a special detergent.

3, AUSTENITIC GB4237 1Cr12 stainless steel surface with bleach and various acid adhesion, rinse immediately with water, then dilute with ammonia solution or neutral carbonated soda aqueous solution, wash with neutral detergent or warm water.

4, AUSTENITIC GB4237 1Cr12 stainless steel surface has a rainbow pattern, is caused by excessive use of detergent or oil, wash with warm water detergent can wash.

5, AUSTENITIC GB4237 1Cr12 stainless steel surface caused by dirt, can be washed with 10% nitric acid or grinding detergent, can also be washed with special washing drugs.

As long as we use the correct maintenance method, we can extend the service life of AUSTENITIC GB4237 1Cr12 stainless steel.
