316L Stainless Steel Plate

Name: 316L stainless steel plate According to the test: 316L stainless steel plate due to the addition of Mo, corrosion resistance, in particular, excellent resistance to pitting, high temperature strength is also good, excellent processing hardening (weak magnetic after processing), solid state non-magnetic.

Corrosion Causes 

1. The stainless steel surface is accumulation with other metals or other metal particles of the attachment. In moist air, the condensation water between the attachment and the stainless steel connects the two into a micro battery, triggering the electrochemical chemical reaction, the protective film is damaged, called electrochemical corrosion.

2. Stainless steel surface adhesion organic juice (such as melon, noodle soup, phlegm, etc.), in the case of water and oxygen,organic acids are formed and organic acids are corroded on the surface of metals for a long time.

3. Stainless steel surface adhesion containing acid, alkali, salt substances (such as decoration wall of alkali water, lime water spray splash), causing local corrosion.

4. In polluted air (e.g., atmospheres with large amounts of sulfide, carbon monoxide, nitrogen oxides), cold condensate, the formation of sulfuric acid, nitric acid, acetic acid liquid point, causing chemical corrosion.

The above conditions can cause corrosion of stainless steel surface protective film.


Cause of Rust

When the stainless steel surface brown spots, people are surprised: "stainless steel will not rust, rust is not stainless steel, may be a problem of steel." In fact, this is a lack of understanding of stainless steel One-sided wrong view. Stainless steel can rust under certain conditions.

Stainless steel has the ability to resist atmospheric oxidation, which is not rust, but also has the ability to withstand corrosion in the medium containing acid and alkali salt, that is, corrosion resistance. However, the size of the corrosion resistance is changed with the chemical composition of the steel itself, the condition of the use of the mutual state and the type of the environment medium. Like 304, in a dry, clean atmosphere, There is absolutely excellent corrosion resistance, but move it to the seaside area, in the sea mist containing a lot of salt, will soon rust, and 316 stainless steel is doing well. Therefore, not any kind of stainless steel, at any time can be corrosion, not rusty.

Stainless steel is formed by its surface of a very thin layer of stable and solid rich chromium oxide film (protective film). To prevent oxygen atoms continue to penetrate into the oxidation, and to obtain corrosion resistance. Once there is a reason, the film is constantly destroyed, the oxygen atoms in the air or liquid will be constantly isolated, forming loose iron oxide, The metal surface is constantly corroded.
