Generally speaking, stainless steel does not rust. However, stainless steel can rust if it is not used or maintained properly, or if the stainless steel is placed in too poor an environment. When we see yellow or orange rust spots on the steel surface, we can quickly confirm that it is a sign of rust.
So how to maintain stainless steel kitchen utensils?
The maintenance method of stainless steel has been introduced in our previous article. I won't go into too much detail. If you want to know, just click on that method.
Today, I want to talk about why stainless steel kitchen utensils rust.
1. There are dust or dissimilar metal particles attached to the surface of stainless steel kitchen utensils containing other metal elements. In humid air, condensation between the accessories and the stainless steel connects them into a tiny battery, causing an electrochemical reaction and damage to the protective film, called galvanic corrosion.
2. Organic juice (such as melon vegetables, noodle soup, etc.) is attached to the surface of stainless steel kitchen utensils, and it forms organic acid when it encounters water and oxygen. Over time, the corrosion of metal surfaces by organic acids will decrease.
3. The surface of stainless steel kitchen utensils contains acid, alkali and salt substances (such as alkali water and lime water splashed on the decorative wall), causing local corrosion.
4. In polluted air (such as atmosphere containing a lot of sulfides, carbon oxides and nitrogen oxides), the formation of sulfuric acid, nitric acid and acetic acid liquid spots in the presence of condensate, causing chemical corrosion.
Why are stainless steel kitchenware so easy to rust? That's because there is a passivation film on the surface of stainless steel. In the kitchen, chloride ions are very active.
Because salt is used for cooking, chloride ions can damage the stainless steel's membrane and cause it to rust, just like stainless steel in coastal areas tends to rust. Because chloride ions are more active in Haiti, in order to prevent stainless steel kitchen utensils from rusting, they need to be cleaned frequently, so use a washing machine. Wipe with a dry cloth after washing, that's the point.
When buying kitchen utensils, you should look at the material of stainless steel, usually 304ss. If you want to buy good kitchen utensils, you should buy 316ss material. Remember, don't be greedy for small things, so as not to be deceived.
How long is the service life of stainless steel tableware?
Stainless steel cutlery feels like it's built to last, but honestly, it doesn't always rust, so it has its own lifespan too.
Of course, it is a type of stainless steel after all. Although it is easier to rust, its service life is longer than that of iron or other metals, but the specific time should be known through material analysis.
The service life of stainless steel tableware will not rust for 4 or 5 years under normal conditions, but the surface will be blurred and the texture will deteriorate after long-term use. If it's outdoors in some coastal cities, it will rust faster.
Because the air in these places is relatively humid, if it is placed on the beach and soaked in seawater, this seawater with alkaline corrosive components will cause ordinary stainless steel tableware to rust in a short time.
If you want the stainless steel tableware to have a longer service life, it is recommended to place it indoors, and do not let the product come into contact with some corrosive items such as vegetable soup, acid-base lotion, etc. in daily life.
Generally speaking, the service life of ordinary stainless steel tableware is related to the use environment. The drier the environment, the longer the life of non-corrosive objects.
Therefore, it is recommended that if you want the ordinary stainless steel tableware to have a longer service life, you should try to place it in some good environments.
