Description

In fact, all things have a long life. Stainless steel is also a kind of metal. It is a phenomenon in which metals are oxidized and corroded in nature, causing rust. The only difference is the difference in material or degree of protection, which can delay rusting to the utmost extent. The odds and time. However, in many cases, stainless steel will also be “rusted”. Here are some of the “culprits” of rusting Stainless Steel Laundry Cabinet :

1. the presence of chloride ions in the environment

Chloride ions are mainly found in purifying liquids and gases. The use of stainless steel in the presence of chloride ions will accelerate the corrosion even beyond ordinary low carbon steel.

2. without solution treatment

Solution treatment: refers to heating the alloy to a high temperature single-phase zone to maintain the temperature, so that the excess phase is fully dissolved into the solid solution and then rapidly cooled to obtain a heat treatment process of the super-saturated solid solution.

The purpose is to fully dissolve the various phases in the alloy, strengthen the solid solution, and improve toughness and corrosion resistance, eliminating stress and softening, in order to continue processing or molding.

If the alloying elements are not dissolved in the matrix material, the matrix structure alloy content is low and the corrosion resistance is poor.

3. Natural intergranular corrosion

A corrosion phenomenon caused by stainless steel under the action of corrosive media is called intergranular corrosion.

Stainless steel that produces intergranular corrosion, when subjected to stress, breaks along the grain boundary and almost completely disappears. This is one of the most dangerous forms of failure of stainless steel.

Stainless steel does not rust because both chromium (Cr) and nickel (Ni) levels meet certain standards. These two alloys are the key to whether or not steel can prevent rust.

Generally, stainless steel produced by small factories still rusts. The main reason is that the nickel content is too low. If the nickel content is higher than the standard required for all kinds of stainless steel, it will not rust anyway.

4. Mechanical stress corrosion corrosion When stainless steel products are made into products, they need to be stamped, sheared, punched, stretched, ground, sheared, bent, sliced, hot cut or welded.

These external stresses cause a large degree of self-stress damage to the processed part and its edges, causing its intergranular phase transition; thus destroying its own anti-corrosion properties and accelerating its rusting process.

5. Destruction of surface passivation protective layer

Passivation is a method of converting a metal surface into a state in which it is not easily oxidized, and retarding the corrosion rate of the metal.

Passivation is due to the action of metal and oxidizing substances. When applied, it forms a very thin, dense, well-covered, passivation film firmly adhered to the metal surface.

Once this layer of “protective film” is destroyed by external forces (mainly large-area scratches), stainless steel is like a body that is not resistant, and it is easy to oxidize and corrode with the outside world.
